Crunch Labs plays a game called "Will it Float?" and tests various objects with different methods, such as using a hair dryer, air compressor, and leaf blower. They explain the physics behind why certain objects float or do not float, such as the curvature and weight of the object and the low pressure bubble created by the air flow. They also demonstrate a frictionless way to roast a hot dog with an air compressor and flame thrower.
1. The video is about a game called "Will It Float" using different objects.
2. They first try a ping pong ball and a tennis ball with a hair dryer.
3. The tennis ball does not float due to its weight.
4. They then use an air pressure line with 100 PSI to see if the tennis ball floats.
5. They try different objects, including a cucumber, a hot dog, a toy boat, a Rubik's cube, and a screwdriver.
6. They explain the physics behind why some objects float and why others don't.
7. They use a leaf blower to blow a beach ball into the air.
