Yards? 300 Yards, not metres. Thank God for that.It is illegal to fire cannon within 300 yards of a dwelling place (section 55 of The Metropolitan Police Act, 1855). You have been warned.

You can measure the speed of light with a microwave and some cheese on toast.
Take out the revolving dish, place the cheese on toast in the microwave (so it doesn't move), and heat it for abar 20 secs.
Take it out and you should see hot spots where the cheese is melting. Measure the distance between two of them and that is approx half the wavelength of the microwave electromagnetic radiation (ie light). The frequency is standard for a given microwave (usually 2.4 GHz), and wavelength x frequency = speed.

I concur.interesting.
So my cheese hot spots measure 6.25 centimetres apart giving a wavelength of 12.5 centimetres.
12.5 centimetres =0.125 metres
.125 m x 2,400,000,000cycles/s = 300,000,000 m/s (which is indeed the speed of light (c) in a vacuum).
NB : Adjusting for the refractive index of light through air (ie in a microwave oven), would adjust the melted cheese distance a little bit.
