Another CO2 experiment with a POP!

This was a super fun experiment, we used an entire box of antacids.  We used some 35mm film canisters that I have had stored for awhile.  You could use any little container that seals.  The kids filled them about 3/4 full of water, dropped in an antacid tablet, snapped on the lid and ran.  The tablet and water create CO2 which makes the lid pop off.  It is soooo fun.  I was so happy that I actually captured the POP on film, it happens so fast. We counted how long it took each one, though we didn't get past 5.
