I used to do this experiment in the "lab in a lorry" when I was a Science and Engineering Ambassador for the Institute of Physics.

Alas, they don't do "calculating the speed of light using a microwave and a pack of processed cheese slices" any more. :¬(

What does it mean?

It means the gubberment is trying to kill us in their quest for fuel:

She has a point ... look at the price of gold now! All those extra rainbows all need little pots of it at their ends. Think of the leprechauns! Won't somebody please think of the leprechauns?

<Removes hat, and thinks fondly of the little leprechauns.>
Maybe we need a leprechaun OXP that adds green-and-gold little ships with "Leprechaun" on the side... :D

Ah yes that experiment - I remember supporting that in the same manner in the LiaL (speaking as another MInstP). That one I recall working quite well, and it was always fun to explain chirality and see how much you could get their hands and arms tied up in knots...

Personally I preferred experiment 3 (complete with the Tacoma Narrows video from the net), plus watching colleagues trying to get experiment 4 to work without ending up all over the floor.

One of the guys kept the wine glass he "shattered" during the Harmonics experiment - it was beautiful - a perfect sine wave all the way round the glass, just above the maximum width point - the top of the glass came off intact - and fitted back perfectly after the speaker was shut down.
