magic of physics. You will need Cup Water Bell jar Vacuum pump and acetone (optional).

Step 1. Fill the cup with water. Use equal parts acetone and water to speed the process.

Step 2. Place the cup inside the bell jar. Step 3. Connect the bell jar to the vacuum

pump and turn it on. Step 4. Watch the water begin to bubble. Step 5. Watch the water turn

into ice as the warmer molecules escape into the vacuum and the cooler molecules clump

together to form ice in the cup. Did you know The lower the air pressure, the lower the

boiling point of water. If the pressure is low enough, water will boil at room temperature.
