An aluminium can, a PVC pipe and a piece of cloth.
What we Do
Place the can on its side on a flat smooth surface like a table. Rub the PVC pipe with the piece of cloth for a minimum of 40 secs.]]> 2020-10-25 07:37:28 UTC https://padlet.com/admin_jiemin_ps/fht8ja2hykn0h514/wish/858942221 Magical Rolling Can https://padlet.com/admin_jiemin_ps/fht8ja2hykn0h514/wish/858944737 Now is the FUN part!!!
Hold the PVC pipe close to the can without actually touching the can. The can will start to roll on its own.]]> 2020-10-25 07:38:59 UTC https://padlet.com/admin_jiemin_ps/fht8ja2hykn0h514/wish/858944737 Magical Rolling Can https://padlet.com/admin_jiemin_ps/fht8ja2hykn0h514/wish/858946214 What we did is a demonostration we can also make it and experiment by using balloon instead of PVC pipe.]]> 2020-10-25 07:39:51 UTC https://padlet.com/admin_jiemin_ps/fht8ja2hykn0h514/wish/858946214 Magical Rolling Can https://padlet.com/admin_jiemin_ps/fht8ja2hykn0h514/wish/858967584 All matters are made up of atoms, which intern is made up of electrons, protons and neutrons. When you rub the pipe with the cloth tiny invisible electrons with the negative charge build up on the surface of the pipe. This is called Static Electricity, which means non-moving electricity.

The Electorns have the power to pull the very ligh objects (with positive charge - protons) towards them like the aluminimum can.

Conclusion
I learnt from this project that rubbing a PVC pipe with the cloth creates static electrictiy. Pipe which has gained the electrons becomes negatively charged. Hence the can which is positively charged is attracted towards it, as opposite charges attract.]]> 2020-10-25 07:52:28 UTC https://padlet.com/admin_jiemin_ps/fht8ja2hykn0h514/wish/858967584 https://padlet.com/admin_jiemin_ps/fht8ja2hykn0h514/wish/858969399 2020-10-25 07:53:27 UTC https://padlet.com/admin_jiemin_ps/fht8ja2hykn0h514/wish/858969399
