Try this as it is written (you may need a little help from your mom)
After the experiment write back and tell me what happened. Let your little sibling help and ask them what they think happened.
Materials you will need:
• Bowl of cold water
• Coin (bigger than the bottle opening)
• Glass Coke Bottle (with a small opening/mouth)
This is magic!
What happens to air’s push when you heat it up?
Air’s pressure or air’s pushing power changes when it is heated.
Steps:
1. Fill a bowl with some cold water.
2. Place the bottle neck and coin in the bowl of water to chill them. This helps to make an airtight seal when you place the coin on the top of the bottle.
3. Place the coin on the top of the bottle.
4. Wrap your hands around the bottle and wait for several seconds.
What happens to the coin?
5. Remove your hands from the bottle and wait.
What happens to the coin now?
Why does the coin jump?
I will post the anserw on Day 4
