Compressed air has great strength. The book blast experiment is a science project that demonstrates just how powerful it can be.
What You'll Need:
- 3 books
- Large airtight plastic bag
Step 1: Challenge a friend to move 3 books stacked on top of one another on a table by simply blowing at them. Of course, your friend won't be able to do it!
Step 2: Place a large plastic bag on the table, and put the 3 books on top of the bag. Leave the open end of the bag sticking out over the edge of the table.
Step 3: Hold the opening together, leaving a hole as small as possible. Blow into the bag. Take your time; stop to rest if you need to.
If you blow long and hard enough, the books will rise off the table. They will be supported by the compressed air in the plastic bag.
The next science project simulates a storm inside your own home. Keep reading science projects for kids: air pressure.
