Step 1: Materials Needed
1 - 1/4" x 20 nut - $0.06 Link to product on HomeDepot.com - This is a link to a box of 100, but you can buy just one at Home Depot
1/2 stick Mighty Putty - ~$5.00 Link to product on Amazon.com
1 - box knife - Example of the kind of knife I used
Time Required: 20 minutes assembly, 24 hours to let the putty cure
Step 2: Cut 1 Stick of Mighty Putty in Half
After the blob is uniform in color, mold the putty around the half of the tarp shark that looks like the tail. This is not the side with the teeth. Make sure to cover all of the plastic with the putty and tap the shark on a piece of wax paper on a table to flatten out the bottom of the putty.
