Super cold LN2 replacement experiment – create an ultra-cold liquid nitrogen replacement using alcohol and dry ice.

Pouring liquid nitrogen into a plastic container

Liquid nitrogen, represented by the equation LN2, is often used in higher level science experiments. In this experiment, we’ll create a liquid with the same “ultra cold” properties found in liquid nitrogen. You’ll need two plastic bottles, one slightly smaller than the other.

Ever had a hot, steaming cup of Oobleck? Geez, I hope not. The stuff is nasty! But it does exhibit some interesting properties. Read on and learn how to make Oobleck slime!

Chemical reactions occur every day all around us. A chemical reaction is a process where one type of substance is chemically converted to another substance. That fizzling toilet bowl cleaner is a chemical reaction. The fire in your fireplace is another type of chemical reaction. The smoke that comes out of Dad’s ears when you…

In this science experiment we will introduce you to a principle called osmosis. Using simple household items we will demonstrate what osmosis is and how it works.

Make your own silly putty or green slime and then take a dab of green slime and wipe under your nose. Then tell Mom you’re not feeling well. Or take the brown silly putty and place a lump on Dad’s chair right before he sits down. When he stands up make a scrunched up face…

Everyone knows recycling is good for our environment, but do you know how the recycling process is actually done? In this experiment, we’ll recycle a newspaper into nice, neat little sheets of fresh paper.

Invisible ink has been used by spies for centuries. At the time of the Revolutionary War, invisible ink made of a mixture of ferrous sulfate and water was commonly used. The secret messages were often written in between the lines of a normal letter. When heat or a special chemical (such as sodium carbonate) were…

Fire extinguishers work by removing one of the critical ingredients for a fire – oxygen. In this experiment we demonstrate this process.

Alcohol water burning five dollar bill experiment

In this experiment, set a five-dollar bill on fire and laughing madly as it burns. The flames will mysteriously snuff themselves out and the five-dollar bill will be left unharmed. Hmmmm… Is this science or magic?

An aluminothermic reaction with Iron(III) oxide; as known as a thermite reaction

Zinc does not occur freely in nature but does exist in the ores of other metals. Zinc was widely used centuries before people knew what it really was. For instance, Romans use to smelt copper ores that contained zinc and were making weapons out of brass without even knowing it.
