The heating of water in the microwave can actually be dangerous? Watch the video and see the potential hazards involved with this everyday activity. Water alone should never be heated in a microwave. Watch and find out why.

No matter how many times I do this, I never get bored making it. Imitation silly putty. It acts like snot but it isn't sticky. It flows like slime but isn't greasy. The best part is you can make this "Silly Putty Like" substance at home. All you need is Borax and Glue.

Electroplating A Quarter

The term "Thermite" refers to the mixture of aluminum and ferric oxide used in this experiment. It is sold commercially and is used for such applications as railroad welding and incendiary bombs. Rust and aluminum are combined and ignited with a magnesium ribbon. Molten iron is produced and lots of energy is released. This demonstration produces heat at above 2800F or 1500C. Fe2O3 + 2 Al --> Al2O3 + 2 Fe Safety-This is an extremely DANGEROUS reaction and should only be done by trained professionals. Since YOU are not a trained professional DON"T try it.

This demonstration is used to confuse and spark the interest of all my students. I usually throw the water at them at the end of the demonstration. Unfortunately there were no volunteers when I made this. Enjoy the trick, I posted how to do it in another movie, if you are interested

Can water boil at room temperature? For water molecules to escape from a liquid and become a gas they have to overcome atmospheric pressure. ... Ordinarily, that means that you have to heat the water up to 100 degrees Celsius, where its internal (vapor) pressure becomes 1 Atm. However if the atmospehric pressure is lowered (like in a vacuum jar) the water can boil at a much lower temperature.

WARNING*** WATCH THE VANISHING WATER TRICK FIRST This video reveals how the vanishing water trick is works. It is not magic but chemistry.
