Re: Escape the Frictionless Circle

Sort of a trick answer: Pick apart the rope. You should be able to acquire three 50-metre strands without breaking your connection to the gold brick. Form these into one long, thin rope, and throw it to the outside of the circle where it can make contact with the friction area (a loop at the end...

Re: Another smullyanesque puzzle

Correct. By the way, I was expecting that somebody would give the obvious answer to the second question: "gay". See, I didn't think that at all. In Le Morte d' Arthur, only chaste knights are allowed to see the Holy Grail. In The Once and Future King, Lancelot spends pages and pag...

A contractor was going to build a bridge from the island to the mainland. He pulled out his protractor to measure some angles 'n' shit. The two ions reacted to leave a single tractor of mass equal to the sum of protractor and contractor but with no charge upon it. If you think you can include a con...
