Hi guys

Here is something a little different for you to watch and maybe experiment with. If you do, be careful and please show us some pictures/videos of what you do.

Ok guys. Does that mean we have to have a poll to see if it's "hot" or "cool"?

Cheers

It is amazing what sound can do. Thanks for the link. I just found these a few minutes ago. It has nothing to do with fire but is impressive none the less.

This guy is - I'm guessing - a physics teacher. It was a man like him who led me to pursue Chemistry. We called him "Mr. Chips" (a good name for a machinist) and he'd show up in a Wizard outfit and put on some incredible demonstrations.

Teachers like him are worth their weight in gold.

Reminds me of a "FogScreen", whereby images are projected onto a wall of smoke or mist that has a more or less smooth flow to it.

I agree: teachers like that are worth their weight in gold. And they should be paid to keep teaching, not to be "promoted" into management.

The first one was a great demo of the relationship between frequency and wavelength.

The Japanese one reminded me of a (long ago) description of the Bessel functions used in calculating sidebands in FM - cheez, where did that come from? :
