Asked by Kearse

I have to design a gadget that will either: light a match, pop a balloon, cause something to change color, lift a 500gm object at least 5cm, Blow out a candle, and/or turn on a light bulb.
This experiment can be done by either using baking soda and vinegar or Alka-Seltzer and water. Please help!
I can blow up a balloon but it will not pop what am I missing?
Thanks

Put the balloon above the candle, the candle will burn a hole, and the carbon dioxide should put theflame out.
