Want to have a trick for Halloween? Well, you can pick this experiment. You need: a piece of paper, candlesticks, sunscreen, cotton balls (optional), some red stocking, scissors, someone to watch you like a big Halloween group and last, but not least a table.
Step one: put the paper on the table
Step two: put the red stocking on the paper
Step three: put the cotton ball on the paper, remember to wet the cotton ball with special water.
Step four: use the cotton ball to write a message like "Happy Halloween" or "wow" -- did it work?
Step five: trim paper to size and show this to your Halloween group
Step six: rub the candlestick(s) on the paper, but make sure your group does not see this step
Step seven: put your hand on the piece of paper - this time your audience can see - does it show your hand outline?
How does it work?When you press the water[ see Simple experiments} it goes on to the red stocking and it
turns into the same color of the stocking.The red liquid doesn't stay on the paper forever.Why? Like most liquids like milk it washes away. Also some liquid contains a special so it can wash away.
