• Materials: Clear drinking glass, a piece of paper or tissue, and a bucket.
• NOTE: The bucket must be taller than the glass and the paper must fit half way up the drinking glass.
• Experiment: Fill the bucket between halfway and 3 quarters of the way
• Make the paper into a ball and put it in the bottom of the drinking glass.
• Turn the glass upside down. The paper ball must stay in the bottom of the glass. If it falls out make the paper ball bigger.
• Hold the glass upside down and put it in the bucket that has water in it. Make sure the glass touches the bottom of the bucket.
• Pull the glass up but DO NOT TILT the glass as you pull it up.
• Examine the paper. It should be dry (if you did it right).
• Why: The glass is filled with paper and air. The air prevents the water from going into the glass keeping the paper dry.

• Materials: cola bottle or any other small mouthed bottle, and a balloon
• NOTE: The balloon mouth must fit over the bottle mouth.

• Experiment:Hold on to the top of the bottle and push the balloon inside the bottle.
• Stretch the top (or part you blow in to) over the mouth of the bottle.
• Try to inflate the balloon.
• The balloon only expands slightly (if you did it right).
• Why: The bottle is filled with air molecules. Blowing in to the balloon makes the air molecules go closer together. Making the balloon inflate only a little.
• All experiments from the book Janice VanCleaves Chemistry for every kid.
