You know the idea. Mentos plus 2L soda equals big fat fun. I am trying to do a weekly science experiment with these kiddos, so we tested which soda would shoot the highest. Root beer won, but they just loved making the mess. Total cost was: $5.64
4 X .75 = $3(mentos) and .66 X 4 (soda) = $2.64
She mixed all the left overs together and drank some.
Max just carried around this empty bottle for a few hours. Why?
