To make the trivet, all you need are corks, an adjustable metal pipe clamp and a screwdriver. Here's what you do:
Gather up your corks (real or synthetic), and arrange them inside the clamp. The corks should be densely packed together, so there aren't any loose corks falling out later. With the screwdriver, tighten the clamp around the corks.
That's it! And now you've got another excuse to open a bottle of wine tonight.
