Very cool, happy to hear it!

I was waiting for Karen's reply about the Tyndall Effect, before explaining what it was.
Remember your experiments in the chemistry classroom when something went bang, changed colour, or whatever. You just had to find out why, ( sodium on water for example).
Something strange that you have to explore, just to fill her day with.

Ah, sorry if I spoiled the fun! :O

the first time you see the effect it is spectacular.

It is pretty impressive, especially if you've done a "before" and "after" test... ;)

That is what I was hoping to show Karen.
Flashy pesudeo science works every time.
