This question got sent in by Jacinta of Coburg.  But rather than just an an answer from me, I thought I’d open it up to the public so you crazy kids can strut your smarts and win a prize – lets see how you do!

You have two pieces of rope which each burn for exactly one hour. The ropes are not made of the same materials as each other, and each rope is not made of the same materials in its length either. Both ropes will catch fire easily, and burn for exactly one hour, but it is possible that (for example) one might take 52 minutes to burn 25% of its length and then 8 minutes to burn the remaining length, you don’t know.
You have no other form of timing device, no phone, no watch, no clock, no sundial, no sun.
You have a few matches in a match box.
How do you measure out exactly 45 minutes?

Now my sexy superior intellect (or my relatively attractive and average brainpower at any rate) was able to figure out an answer in short order (hint: it involved quantum mechanics and a tapeworm).  But can you? And WITHOUT Google’ing it?  Put your answers in the comments section below.  At the end of June we will pick the answer which is either the most accurate (and obviously not online researched) or the most entertaining and give it it’s own post!

The winner will also receive either

A: A hand-written delicious brownie recipe from Jacinta or

B: A pack of Transformer Top Trump Cards from me.

Lets see those brains working people – good luck!
