Expanding Baby Bottle

We’re excited to re-introduce this classic science demonstration made popular by the original Mr. Wizard, Don Herbert, who was a master of creating unforgettable experiences using household items. 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! There’s 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. It’s a classic science demonstration for a new generation.

What's included?

• Plastic baby bottle
• 3 "Blind" baby bottle nipples (nipple without a hole in the tip)
• 4 Alka-Seltzer™ tablets

What does it teach?

After performing this "signature" demo for 30 years, Don Herbert discovered a problem with the rationale for doing the experiment in the first place. Now, you can help your children wonder and discover the real lesson behind the demonstration.
