How much gas is trapped in two tablets of Alka-Seltzer? Mr. Wizard answered the question by trapping the bubbling gas inside a baby bottle, but the top of this bottle has no hole! Theres so much bubbling carbon dioxide gas being released that the baby bottle top expands to an enormous size. The audience reaction will be a mix of screams and laughter. The kit comes complete with a plastic baby bottle, three hole-less rubber tops, effervescent tablets and an activity guide, which includes an updated version of the original demonstration taught to Steve Spangler by Don Herbert. Its a classic science demonstration for a new generation.
