Sugru is a self-setting rubber for fixing, modifying and improving stuff. It molds like play-dough, bonds to almost anything and turns into a strong, flexible silicone rubber overnight. It comes in several colors, and is great for all sorts of things.

Most phone cases are cute, but don't provide enough protection for a real drop. Let's put some bumpers on the case corners to keep your phone safe.

Supplies-
Sugru in the desired colors (You can mix colors if you like!)

Step 1: Open the Sugru

The Sugru comes in little metallic packets to help keep it fresh. There's dotted lines on each packet showing where to cut the packet open. Go ahead and cut open these three sides, peel the packet open, and scrape the sugru out.

Step 2: Knead and Mix the Sugru

Knead it up for about 30 seconds to get it activated. This is a good time to mix up different colors! Your working time with Sugru is only about 30 minutes, so don't take too long.

Step 3: Divide Up the Sugru

A little goes a long way with this project. For each packet of Sugru in your mix, divide it up into 4 equally-sized pieces. If you've mixed two packets of Sugru to make a new color, divide it up into 8 pieces! (You'll probably have more than you need for the corners, so you may have some left over.)
