Hydrogen Bomb Ingredients: * 2-liter bottle * hydrochloric acid (HCl) (The Works toilet bowl cleaner) * aluminum foil * balloon * long wick Procedure: * fill the 2-liter bottle with 20 or so strips of 12" long X 1" wide loosely rolled aluminum foil * add 8 oz of HCL to the bottle * shake and remove cap (be sure to cap before shaking) Note: If you need more detailed instructions on how to complete the prior part, see How to Build a Pressure Bomb * Place the balloon over the top of the bottle to catch the Hydrogen (H) gas that will escape from the bottle * when the balloon has expanded, place the wick partly inside it, and tie the ballonn in a knot. Note: Hydrogen is lighter than air, so if you release the balloon, it will float away (This could be useful...)
