Well here is my water hazard! This is done in 3 pours to get the 1/2" thick edge. Note that I made a dam from Drafting tape. I tried the blue tape in the past but it reacted with the glue in the tape and leaked the acrylic. Regular tan masking tape seems to work best. The acrylic I used is the standard one available at Hobby Lobby. See my technicques tab for more information there. Nothing really complicated here, just read the instructions on the can and go. I did this one over 2 days to get a good cure, but you could do it in the same day. .
Whatever your hand finds to do, do it with your might.
