Larry's Lab - Polymer Science Kit

Larry's Lab - Polymer Science Kit

Explore the molecule-twisting, mind-bending chemistry behind polymers with our favorite collection of water-absorbing powders, crystals and spheres. We can't imagine a better kit to supply you with all of our erupting, growing polymers in one pail.
Test Tube Wonders Kit

Test Tube Wonders Kit

It’s a science lab in a bag. Make up a pile of Insta-Snow, experiment with waterproof sand and explore the science of UV light as you use the sun to make white beads instantly change colors. Grow a test tube dinosaur, learn how to make water disappear and make squishy jelly crystals. Recommended for children 8 and up.
Water Jelly Crystals

Water Jelly Crystals

These amazing pebble-sized polymer crystals grow into huge pieces of gel-like material when you add water. Explore the science of superabsorbent polymers.

Exploding Water Experiment Hits Home for Reader

'Tis the season for spending time in the kitchen making those holiday feasts. So, when we were choosing a timely experiment to send in our Experiment of the Week email, we figured that Exploding Water in the Microwave was a great choice to make sure everyone had a safe and happy holiday.  Our choice was affirmed when a reader took the [...]

July 4th Science – Exploding Watermelons

Over the years, the exploding pumpkin demo is right up there at the top of my short list for my all time favorite, crowd-pleasing science demonstration. But who wants to wait a whole year just to do the demo again? That's why we're working on the fine art of watermelon carving... with the aid of a tiny chemical reaction... okay, it's [...]

Exploding Watermelons

I love Halloween. One of my favorite activities is to "carve" pumpkins using a simple reation inside the fruit. First, you carve the face then carefully replace pieces. After creating a reaction by generating a gas inside and igniting it (ask your local chemistry teacher for the details) the face pieces are blown off with a small explosion. Halloween is more than [...]

Patriotic Monster Foam – Exploding Hydrogen Peroxide

Since fireworks are no longer an option, you have to find some way to occupy your time on the 4th of July. I turned to my demo team and brainstormed anything we could do in the backyard at 9News for the celebration. Here's the classic Elephant's Toothpaste demo using hydrogen peroxide and potassium iodide as the catalyst to make a red, [...]

Hydrogen and Oxygen – Exploding Soap Bubbles

Combine two parts hydrogen with one part oxygen and you get water and a little energy. Unlike traditional hydrocarbon fuels, hydrogen and oxygen do not produce any bad bi-products for the environment. This is an incredible, renewable source of energy. It is also the idea behind fuel cell cars. Meteorologist Becky Ditchfield at the NBC affiliate in Denver wasn't so sure about [...]

The Incredible, Edible Exploding Egg

Do not try this at home. Instead, watch your chemistry teacher perform this demonstration. If you know me, you know I don’t do things the easy way. I do things the explosive way. If there is a flame involved, I’m all over it. So I decided to make use of all of the left over Easter eggs this week and crack [...]

Water Can Explode in the Microwave

Did you know that heating water in the microwave can actually be dangerous? While sharing this story with audiences, I've learned that many people have had similar experiences but never understood why the water just blew up. It's an important piece of science to share with others in hopes of preventing a potential disaster. The American Burn Association (ABA) has identified scald burns [...]

Steve Spangler on The Ellen DeGeneres Show

When someone is as awesome as Ellen DeGeneres, people tend to listen to what that person has to say. So when Ellen says, “Steve Spangler is the science teacher you always wanted to have in school,” we get pretty hyped-up around the office. That excitement is tenfold when it's Steve Spangler on The Ellen DeGeneres Show. We shouldn’t be surprised, really, that [...]

Don't Miss Your Best Chance to Study Electrostatics

By Christy McGuire, For those of us who live in the United States it is winter time right now.  Most people think about snow as the main scientific aspect of winter.  Some may even think about the increase in darkness.  However, for most of us, winter also means your best chance to do electrostatics and have your demonstration actually work. Electrostatics are all those [...]

Halloween Science Activities from The Spangler Effect

Thank you for joining us on The Spangler Effect Live this week for our last minute Halloween science demos and activities. During the two hours, Steve and Higginsworth shared a lot of fun, messy and loud experiments for spooky fun. If you missed the broadcasts, we have both available in this post. If you want more information on any of the [...]
