when u were young did u used to do finger paints and what not?well i have!well there are more fun projects than just that!when i was about 6 years old my dad had some soda bottles.and what we read in a book was that you take a empty beer/soda bottle and put it in the freezer.than after about 5 hours take the bottle out of the freezer and put a coin over the top of the bottle.and for the last part just watch it.soon u will see the coin move.this trick is called the ghost in the bottle.dont go anywhere.ill be back with more ideas.
