Pour about 1/4 cup of popcorn kernels to the pan, and add a few tablespoons of oil. Click the link to determine the other interesting experiments can be achieved using copper sulfate! Real tin foil these days is used more for things like electrical capacitors than food prep or storage. The two forces at work here are gravity and the buoyancy created by the barge as it displaces some of the water. Its likely theyre using it to bake out their equipment, the same as does SLAC National Accelerator Lab. First, pull off a sheet of aluminum foil that is about twice as long as the pan. Did you make this project? This is opposed to insulators, which don't allow charges to move freely through them. Good popcorn is great, but most popcorn rarely lives up to its aroma. After this step it's important to keep the pan generally upright so you don't spill the oil. Is the efficiency for all food items more or less the same? Kids learn through play- teach letters, shapes, numbers, & colors with foil! We needed a way to make it look more like the texture of the moon so decided to crinkle it up into a ball (the kids will love this ;)!). 1.
