Capture a rainbow in a tube with squishy jelly crystals that you grow and color yourself! Watch the colors mix and create a burst of rainbow jelly crystals.
This fun science kit has three cool activities in one giant, reusable test tube. Explore the magic of chemistry as you watch chemical reactions in action with fizzing tablets turn regular water into colored water. Next, grow big squishy jelly crystals overnight. Then you’ll be amazed as you create a rainbow in a tube using the magic of science! You’ll learn about the incredible superabsorbent polymer that drinks up to 300 times its weight in water, and about the secrets of the giant test tube, that comes from a very unusual place and can be reused for science experiments again and again. What will you think of to explore?
What you'll get:
- Giant, reusable test tube
- True Color fizzing dissolvable color tablets
- Clear “Rainbow Crystals”
- Activity Guide
Incredible Science Fun Learning Ideas:
- Learn about chemistry and applied science with this kit.
- Discuss hydrophilic properties and superabsorbent polymers.
- Tons of amazing science properties are at hand. Proper name for these water jelly crystals are "cross-linked polyacrylamide copolymer gel". Good luck saying that 10 times fast.
- Learn how these crystals help preserve water in the soil, especially during drought conditions.
In addition, the Super Tube itself has an interesting background and offers even more scientific activities.
Scientists use test tubes of all different sizes and shapes to study and collect really cool things. A test tube can hold a liquid like water. A test tube can be used to collect samples of many different small items.
What makes this test tube so great? Most test tubes are made of glass. This test tube looks like it's made of glass but it's really plastic. It is hard to break if you drop it but there's something else special about this test tube. What are those grooves on the top? It kind of looks like the top of a bottle...a plastic, 2-liter soda bottle to be exact.
The Test Tube looks like a Baby Soda Bottle. It's modeled after the plastic forms that are sent to the bottling company and blown up through a molding process into a 2 liter soda bottle. Very hot air is blown into the test tube and this makes the plastic stretch like a balloon and fills the inside of the mold. It grows about 40 times its original size!
Warning: choking hazard Small parts. Not for children under 3 years of age.
