How to Make CO2 bomb
Let us make a CO2 bomb. One will need the following: 2 sparklets, a 0.5 liter bottle half filled with water, a hammer and some nails. Hold the sparklets under your foot and punch nails in them. Then, quickly twist the cap to the bottle. Wait for the bottle to grow in terms of its size slowly and then kabooom! It acts like a time bomb depending upon the pressure and the size of the bottle. Try it for some kick-ass fun.
