Alcohol bottle in a block of ice: How can I make a mold ? Answered
I tried by making a rectangular wooden box, cut in half, with piano hinge on one side and clasps on the other sealed with silicone on the edges. Very hard to get water tight. I somehow made a successfull mold, but not good for multiple use. Water seeps through the wood (even after varnishing), i am looking for an easy solution.
