Place these tiny, solid spheres in water, and in just a little while you will have your own Jelly Marbles. What starts out as a 3mm pebble, quickly becomes an approximately 20mm ball of jelly! These water beads absorb a lot of water, plus they maintain their spherical shape when they are done growing.
They teach a valuable lesson about the power of polymers!
Go beyond glue slime and make the world’s best slime using Steve Spangler’s Slime Art. Each kit comes with three colorful 240 mL (8 fl oz) bottles of high quality PVA (polyvinyl alcohol), and a 240 mL (8 fl oz) bottle of Slime Art Activator solution.
3 Amazing Colors of Slime Art!

Magic Sand begins as normal looking sand, until it’s dyed and coated with a substance that repels water. This coating keeps the sand dry even after it has been dumped into a container of water. Build castles and other structures under the water, then simply pour the water off when you’re finished and the sand is still dry! You can use it for fun science experiments again and again! Colors vary.
It's a hydrophobic polymer! Yes, sand that never gets wet!
This superabsorbent polymer absorbs water to become a slippery, slimey, “anti-gravity” goo! The resulting liquid, defies gravity as it climbs up and out of a cup. Gravi-Goo is a great introduction to molecular weights and structures. Children will marvel at this fascinating goo and learn a lesson about polymers at the same time!
Sippery, slimy substance that seems to defy gravity
Place each dinosaur in water and watch them grow to an amazing size of 10 inches (25 cm) and more. Learn about the science behind these growing dinosaurs and try some fun science fair experiments along the way.

These colored spheres are much like Jelly Marbles, but they never lose their amazing color! Mix them, squish them, bounce them and count them, but they will never fade! These little polymers are great for counting and classification… we even provide the Count and Classify worksheet.
Explore the science of polymers
These amazing pebble-sized polymer crystals mysteriously grow into huge pieces of gel-like material when you add water. In fact, these crystals absorb 150-300 times their weight in water! Because of their incredible thirst, they’re even used to reduce the amount of water needed to water crops and gardens during years of drought!
Discover how polymers perform very important functions in everyday life
You may never know when snow is about to fall, but with Insta-Snow® powder from Steve Spangler Science, you can have the next best thing. The process to make realistic, fluffy snow is incredibly simple! Now just pour two ounces of water over the snow and watch the dry, white powder erupt into a miniature mountain of Instant Snow!
As seen on The Ellen DeGeneres Show, The Today Show, & Good Morning America
Also known as slush powder, this powder instantly turns a liquid into a solid. Sodium polyacrylate absorbs from 500-800 times its weight in water and is actually the secret ingredient that’s used to absorb “liquid” in baby diapers! Includes a science activity guide with lots of fun polymer tricks to play on your friends!
Make water disappear like a magician!
Polymer-ologists have searched high and low to bring you the newest polymer sensation… Polymer Cubes. These tiny, squishy cubes grow CAN grow over 200 times their original size when you plop them in water and they help make the connection between math and science with a unique look at geometric shapes. Once you “grow” these water-filled cubes, you won’t be able to put them down!
Connect science and math with this easy-to-measure geometric shape
The Energy Stick is the newest tool in experimenting with open and closed circuits. Completely safe to touch and handle, the Energy Stick features electrodes on each end of its 7.5″ long tube. When these electrodes are touched simultaneously, long-lasting LED lights inside the tube flash and the tube makes a noise. Release one or both of the electrodes and the flashing lights and noise stop. Do it over and over again… it works every time!
The Energy Stick is a great toy to explore the science of electricity and circuits
The Geyser Tube is a loading tube for the now famous Diet Coke geyser powered by Mentos. Attach the Geyser Tube to any bottle of sod. Secure the trigger pin in place. Load the Mentos into the tube, lock the special pressurizing nozzle in place and pull the pin. The Mentos drop into the bottle and the powerful soda geyser comes shooting out the top with enough pressure to reach an incredible height of 9 meters (30 feet). That’s a record!
The Geyser Tube will give you a perfect launch every time
You guessed it… this frog grows to an enormous size when you soak it in water. The frog starts out 8 cm (3 in) long and grows to 23 cm (9 in). Remember, it grows in all directions, so this frog is huge. Dry it out (if you’re patient and careful) and watch it return to its original size.
Just add water. Let your frog sit in the water for two weeks and watch him grow!
This crocodile starts at a mere 12″ in length, but soak it in water and it grows up to three times its original size! That means you’ll have a gargantuan crocodile that is over 25″ in length and can be up to 36!" Just drop Clyde (that’s his name) in a large bucket of water and watch him grow and grow over the next two weeks.
Watch it grow before your eyes and learn about super-thirsty polymers along the way
