Me and my friend found this out a couple of days ago. All you need is an air compressor, a golf ball, and a nozzle that lets you spray air when you press it. You'll find out what I mean in the next step.
This is my first instructable so it is not perfect.
Step 1: Materials
Here is a list of stuff you'll need.
1. An air compresser
2. A golf ball
3. A nozzle
Step 2: Hold It
Hold the golfball about 6 inches above the nozzle. Make sure the nozzle is pointing upward. Be sure to have your hand on the trigger of the nozzle.
Step 3: Blow It!!
Now shoot the air out of the nozzel and let go of the golfball a few seconds later. If you have a weak air compressor hold the ball closer to the nozzle. Now you can turn it to a 40 degree angle and it will not drop. You can use a practice ball and it will go much higher but you can't really turn it sideways so....
