SEE FOR YOURSELF
Materials Needed:
- Two Plastic Cups
- Aluminum Foil
- Match
- Blotting Paper
- Water
Step 1. Put a piece of aluminum foil at the bottom of a plastic cup to prevent the plastic from getting scorched.
Step 2. Soak a piece of blotting paper in water.
Step 3. Light a match and drop it on to the foil in the cup.
Step 4. Quickly, put the blotting paper on top of the cup and place the other cup upside down exactly on top of it.
Step 5. Pick up the top cup when the match has gone out.
You can see that the bottom cup should be attached to it because as the match burnt it used up some of the air, giving a partial vacuum.
