Description :

Great DIY experiment toy to help kids learn the Electrostatic Principle , and cultivate kids interest in physics and science .
Install the experiment device
model as pictures shown , put 2
pieces 1 . 5V AA batteries in battery box , press the button , we will see that the rotation of the fan leaves the foam particles also followed fly fast spin up . A few seconds later , turn off the switch , we found that the foam particles were adsorbed on the inner wall of the plastic cup .

Material : ABS Plastic

Assembled Size ( LxWxH ): Approx . 15 x 7 . 7 x 14cm / 5 . 9 x 3 . 03 x 5 . 51 inch
Experiment Principle :

Due to the limited space , the foam and the inner wall of the plastic cup continue to undergo & quot ; contact separation & quot ; and produce static electricity . When the fan stops , the foam is very light and can be easily adsorbed by static electricity , so we see that they are Adsorbed on the inner wall of the cup without falling off .
