How To: Do the Kaye effect science experiment
Check out how to demonstrate the Kaye effect using shampoo and lanyard with this tutorial. On dribbling shampoo from a small height above a pool of the same shampoo below, every now and then liquid lanyards of shampoo leap forth in a behavior referred to as the Kaye effect. Such behavior is characteristic of a viscoelastic fluid. This is a great science experiment to do with your kids. Watch this how to video and you will be able to create the Kaye effect at home.

Watch this how to video and you will be able to create the Coanda effect with your kids at home.
How To: Do the liquid rope coil effect science experiment
Check out this cool video where you will learn how to create the liquid rope coil effect. Honey is dribbled off the end of a chopstick into a pot below.

A growing column of liquid coils of rope begin to emerge from above the surface of the honey in the pot in an effect referred to as the liquid rope-coil effect.
How To: Create and understand the wet sand effect
When wet sand along the water's edge at the beach is stepped on, it becomes partially dry in a small area surrounding one's foot.

How To: Manipulate your voice with sulfur hexafluoride gas
Lance Lund, a professor at Anoka-Ramsey Community College, was asked to prepare a promotional science video for the college back in 1995 that was to air on a local cable access channel. All went well until he inhaled some sulfur hexafluoride (SF6). The video never aired, but many more of you from around the world will be able to enjoy this right here.
