How To: Blow open sealed containers using liquid nitrogen

In this video tutorial, viewers learn how to do a liquid nitrogen experiment. The materials required for this experiment are liquid nitrogen and film canisters. This task is very easy, fast and simple to do. Begin by pouring the liquid nitrogen into the film canisters. Then quickly place the film canister lids on. The liquid nitrogen will eventually become a boiling gas and expand about 700 times. Because of the expanding, the pressure will build in the canisters and result in popping lids. T...

How To: Grow bacteria with agar & petri dishes

In this tutorial, we learn how to grow bacteria with agar and petri dishes. First, prepare your agar by swirling it and then pouring it into an open petri dish. Next, close the cap to the petri dish and let it sit for an hour. Next, grab a q-tip and swab it on a surface you prefer. After this, swab it onto the petri dish and let it sit for around a week. When you come back to the dish, you will see all the bacteria that has grown! This is a great science experiment to do for children in schoo...

How To: Make your own thin-layer chromatography (TLC) plates

The price of TLC plates can add up. See how to make thin-layer chromatography plates (TLC plates) for a few cents each that are as good as commercial TLC plates that sell for a dollar or two each. You can use these home-made TLC plates the same way you'd use chromatography paper, but the plates provide sharper separations and require far less analyte. They also lie flat, and are much easier to store for later reference. For more information, including step-by-step instructions, and to get sta...

How To: Do a sodium and water experiment

In this video tutorial, viewers learn how to do a sodium and water experiment. Sodium is a silver metal that is very reactive. When exposed oxygen in the air, an outer coding of sodium oxide will form. Simply drop a piece of sodium into a cup of water. When dropped in water, sodium reacts to form sodium hydroxide and hydrogen gas. The sodium will constant move around in the water. Sometimes the heated reaction will cause the nitrogen gas to ignite. Under the right condition, it may even cause...

How To: Chemiluminescence, oxidation of luminol
