This is one of the coolest chemistry kits around! The National Geographic Cool Reaction Chemistry Kit has everything your children need to conduct five amazing experiments. They’ll make messages appear and disappear, create fizzy, bubbling reactions, and more! A detailed experiment guide takes you step-by-step through each experiment and includes insight into the pH science and chemical reactions that make this kit so much fun!

5 awesome chemistry experiments that explore the world of pH science and chemical reactions.

The experiments in this kit demonstrate the principles of:

Acid-base reactions

pH indication and color-changing reactions

Enough materials to do experiments more than once, and includes all the tools you need

Experiments include:

Make it red w/acid

Make it blue w/base

Power of purple (mixture of your acid solution and base solution, creates a purple, fizzing reaction)
