EYE DROPPER OR MEDICINE SYRINGE
Fill bottom of Tupperware with baking soda. Mix vinegar and food coloring in separate container. Have kids fill droppers and drip the solution into the Tupperware. Bubbles, fizziness and fun! I love Callen's tongue sticking out in serious concentration. It was a good motor skill lesson for him as well learning how to hold the dropper and push it so the colors came out. I got shot a couple of times! Great fun! Only takes 10 minutes to set up! Both boys were sad when they ran out of their mixes! Really easy project with instant results for fizzy noisy fun! Carter and I talked about the reaction and he remembered using the same ingredients in school while making his volcano...that will be soon I am sure. I think I will hit the mentos trick for him also soon!
