By Blog Editor Susan Wells

Do you have a pint-sized scientist in your life? Do they want to set up a mad scientist laboratory in your kitchen?

We meet so many parents, grandparents and other influential adults who know a child who is obsessed with science. These supportive adults are constantly looking for new ways to inspire their budding scientist, even if they themselves, are either scientists themselves or completely clueless in the world of science.

One question we are asked a lot is – what do I give the kid who loves science to keep that love alive?

Here are a few suggestions to think outside the box and away from plastic toys and video games.

We sell several different types of all-in-one science kits for kids of all ages, interests and price ranges. Here are the kits, as a mom, I recommend as the best science gifts.

It's Slime Time – Green, Clear, Colored, Glow in the Dark and Creepy Mix-Ins to Spice Up Your Slime Recipe This Halloween

By Blog Editor Susan Wells

Halloween is less than 30 days away and we are getting fired up at the Spangler Labs. One of our most popular Halloween science recipes is for slime. We began years ago with Borax and Elmer’s Glue Slime, then added Cool SlimeGreen Slime, Shaker Slime, Glacier GAKClear Slime and Atomic Slime to our free Experiment Library. This year we’ve outdone ourselves and created an entire Slime Factory and incredibly cool color-changing Vampire Slime.

Green Slime

Slime is the perfect sensory activity or Halloween party activity but it is also a lesson in polymers. Many natural and synthetic polymers behave in a similar manner. Polymers are made out of long strands of molecules like spaghetti. If the long molecules slide past each other easily, then the substance acts like a liquid because the molecules flow. If the molecules stick together at a few places along the strand, then the substance behaves like a rubbery solid called an elastomer. Borax is the compound that is responsible for hooking the glue’s molecules together to form the putty-like material.

Glacier GAK Slime with Borax

Glacier GAK is made the traditional, kitchen science, do it yourself formula. Mix glue, Borax, food coloring and water to get a putty-like consistency. For the complete step-by-step directions, visit our Glacier GAK experiment. We added blue food coloring and mixed it with white glue putty for the effect in the picture above. You can mix up any combination of colors to make a rainbow of slime. This type of slime is more putty-like – highly recommended and fun to last an afternoon.There are several different methods for making this putty-like material. Some recipes call for liquid starch instead of Borax soap. Either way, when you make this homemade Silly Putty you are learning about some of the properties of polymers.

Colored Jelly Marbles Mix-Ins for Slime Factory

If you are looking more for the ooey, gooey boogery slime, we suggest you try using the clear Elmer’s Glue with the Borax or a Polyvinyl Alcohol (PVA) mixture to create the perfect slime. Don’t forget the mix-ins to create your special and unique concoctions like Bug Soup Slime with rubber bugs Fairy Slime with glitter, Lumpy Slime with Water Jelly Marbles or Water Jelly Crystals, or Slime Beads with styrofoam balls. Or go free and clear and make Snot Slime.  AH-CHOO!

Fairy Slime with Glitter

Our brand new Slime Factory – is 128 oz of slime along with all kinds of mix-ins and mixtures.It’s like visiting the frozen yogurt shop but with slime. What would make you happier as a kid than having an entire Slime Factory at your fingertips. The possibilities would have been endless with the limitless imagination of young slime-ologists. This is also perfect for a Halloween or Mad Scientist Birthday Party. Just line the kids up, give them a few pumps and then let them go crazy with the mix-ins.

Vampire Slime is also brand new to our product line this year. Vampire Slime looks green as its mixed up and then turns red in the light. This special mixture was created by Steve Spangler himself and is only available through You will want to get your hands on this for Halloween.

Don’t forget to take time to learn the science behind slime. Scientists call substances like Vampire Slime non-Newtonian fluids. A non-Newtonian fluid behaves like both a solid and a liquid at the same time. When you apply pressure, it turns into a solid (so to speak) and breaks apart. You are breaking the polymer chains apart. When you let slime flow like a liquid, it stretches with no problem as the polymer chains are allowed to uncoil. And, in addition to all that fun chemistry, you get some amazing light science in the special dyes!

We’ve also created a collection of our favorite slime recipes found on Pinterest. There are some very creative bloggers who have come up with their own slime recipes and creations. A recipe for Rainbow Slime from Tot Treasures is a very popular Pin and we can see why. Visit the site for step-by-step instructions to make this very colorful slime.

The Ultimate Harry Potter Science Activities for Halloween or Birthday Parties Part 2

By Blog Editor Susan Wells

Last Friday, I shared my 7-year-old daughter’s Ultimate Harry Potter party and how we created some unique and creative decorations out of science supplies. This was a birthday party, but it can easily be tweaked for a Halloween Harry Potter party or plain old Mad Scientist party.

For the party, I set up different classes and activities to go along with the lessons and teachers in the series. As the kids arrived, I sorted them into houses, by having each one sit on a stool under our Sorting Hat poster. When they sat on the stool, they reached into a bag and picked a ring with a house crest. Several websites sell Sorting Hats or share ideas on how to make your own. This wasn’t a huge focus in our party, so I went with the printable.

After all of the kids were sorted into Gryffindor, Slytherin, Hufflepuff and Ravenclaw houses, they sat down at the tables in the Great Hall, ready for their first lesson.


The first Hogwarts class was Magic. I set it up so that each class had at least two lessons – one as a demonstration and the other as hands-on. The hands-on lessons had take homes for the kids. I built their goodie bag throughout the party.

For Magic, I began with the Magic Coloring Book. I have had my coloring book for a long time and unfortunately it is no longer available. The book helps the kids magically draw, then color pictures as you flip through the pages.

Next, I did the three-cup Monty using Water Gel. Water Gel is a polymer powder that is similar to what is found in a baby’s diaper. The polymer absorbs water. To do this demonstration, ask for a volunteer. Start with three solid cups. Fill one 1/2 way with water. Ask your volunteer to tell you which cup holds the water. Set the cup with the water down with the two empty cups. Mix up the cups and then ask your volunteer to point out the water cup. When they identify it correctly, pick up the cup and pour the water into the next cup and mix the cups again. Ask your volunteer to find the water. When they again identify the correct cup, pour the water into the 3rd cup and mix up the cups again. This time when your volunteer points at the cup full of water, try to pour the water into the 1st cup again. The water doesn’t pour, and your volunteer and audience will be confused. What happened to the water? The 3rd cup contained a scoop of Water Gel powder in the bottom. When the water was poured into the cup, the powder absorbed the water and became solid.

My final lesson was mixing a liquid and making it siphon itself out of the cup. I used Gravigoo for this activity. Gravigoo is another polymer that when mixed with water will make water appear to flow uphill. I let the kids play with the Water Gel and Gravigoo and take a little home in a bag when we were done.


For this class, we held a scavenger hunt. At the craft store, I found rubber spiders, bugs, snakes, rats and frogs. The kids were sorted back into their Hogwarts houses for teams and given a type of animal family (frogs, spiders, snakes, etc) to find. The first group back with all of their creepy crawly creatures won a small prize. This was perfect, because it got the kids up and running around before coming back to sit down for our next class.



As Professor Trelawny, this was my favorite subject. For this class, we turned off the lights and glowed in the dark as we tried to see into the future. First, I made my own large Crystal Ball and told my class what I saw. I saw them becoming true wizards and witches after the party. To make this amazing Crystal Ball with dry ice and a little soap, visit for complete instructions.

I then gave each child yet another polymer…a large Jelly Marble. They could look into their crystal ball and tell me the future. The kids took turns sharing what they saw in their crystal ball. This was so fun and gave each child a time to shine. The giant Jelly Marbles are no longer available, unfortunately, but you can get creative by using smaller Jelly Marbles, water balls, touchable Boo Bubbles, clear marbles, Polymer Cubes (for a twist on the round crystal ball), etc.

To wrap it all up, the kids made Future Telling Wands. I gave each child a Baby Soda Bottle Test Tube. I also had the racks that come with the test tubes to keep everything stable while the kids made their wands. The kids had the choice of making a bubbling lava lamp where we filled the test tube 3/4 full with water and then filled the last 1/4 with vegetable oil. Drop a few drops of food coloring (which can stain) or Color Fizzer Tablets (do not stain). I also added a few drops of Pearl Swirl to make the liquid bubble, swish and swirl inside the wand. For complete instructions and other cool ideas for wands and activities using Baby Soda Bottle Test Tubes, visit our experiments website.


For Charms class, we made Firefly test tubes. The night before I hydrated a large bowl of Water Jelly Crystals. The crystals are polymers that grow in water. After they were hydrated, I put the Jelly Crystals in a plastic bag with Glow Powder. The powder coats the crystals a lot like shake and bake. The Glow Powder glows in the dark. During the party, the kids took handfuls of Glow Powder covered Jelly Crystals and filled their wands. When the lights went off, they had firefly wands to light up the night sky or the Forbidden Forest.


Potions was the perfect party ender and prepped the kids for cake and treats. I began by mixing my own Professor Snape potion, the Purple Paradox. This potion starts as a clear liquid and turns purple before your eyes. Wait a few moments and the potion will turn back to clear. This magic potion is perfect to ward off Death Eaters, but is not for drinking.

After following my careful instructions, my students mixed their own potions. We had different colored sodas available, from Sprite to Orange to Sun Drop. Light-colored sodas work the best. Drop in a tablet or two of Instant Flavor Drink Tablets and watch the color change. The flavor changes too! These drink tablets don’t taste fabulous in plain old water, but mix them into soda and POOF! you have your own potion. Now, dare your friends to drink it.

The kids had a blast making up their own potions and trying them out. They bubbled and changed colors before their eyes. No drink was the same.
Here are some additional activities you can incorporate into your Halloween, Harry Potter or Mad Scientist Party:
