We have a supercool experiment for your next science class, and this one is bound to be a winner! We have already shared ideas on this site for lighting up an LED
Well actually copper-coated zinc coins, to be honest. Because if pennies were solid copper, they would cost more than their value, and Dad might have to pay more tax.
We rely on digital clocks in all kinds of ways, and when their batteries go flat there’s a problem. They tell us when the fries are cooked, and who won the hurdle race.
A party balloon is a battery. Inflate one and release it in the air to convince yourself it is an energy storage system.
Today we are going to show you electrical resistance in action. This is a neat demonstrator for science class.
A battery as we generally know it contains one or more cells inside a case. These convert the energy in their chemicals into the electricity we use
You’ve heard of the many ways of dealing with the plethora of CO2 emissions: reforestation, CO2 capturing and soil sequestering, switching to bio fuels and what have you. However, we bet that you haven’t heard of this new Ethanol strategy! CO2 Ethanol is the new way of getting rid of the excess CO2 we’ve been […]
If you decide to sleep out in a tent at the bottom of the garden, you may want to light a campfire. But if your matches get wet or the lighter runs out of fuel, what are you to do?
We have posted experiments on these pages involving connecting cell batteries in series. These demonstrate how electricity flows like water in pipes when connectivity is good.
The best things in life are free, just as true romance is supposed to be. After that, things can become complicated but that is another story.
