Soda bottle with holes
Heat a nail, while holding it in a pair of pliers, melt several holes
in the bottom of the bottler. Fill the bottle with water and tightly screw
the cap on.carry the bottle back slowly holding it by the cap. The hydrogen
bonding between the water molecules creates a surface tension that holds
the water in. Set the bottle down in the room. Make sure the is a note on
it that says do not touch. When the bottle is picked up, the pressure from
the hand picking it up will cause water in the bottle to shoot out. ever
wonder who is messing around with things. They will be wet if they mess
with this.
