The ultimate portable science lab! Includes several activities for hours of science fun. When you're finished, just put everything back into the bag for easy clean up. Each of the giant test tubes in this kit holds a cool science experiment: learn about super strong bubbles that you can touch, experiment with ingredients to make and mold your own super bouncing ball, write secret messages with disappearing ink that you make yourself and learn about the science of polymers by making a batch of slimy, gooey Insta-Worms. Ages 8 and up.
