Mark Your Cup With Sugru



Introduction: Mark Your Cup With Sugru

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.

Sometimes it's nice to keep the same disposable cup for the duration of an event.  Let's make a unique cup marker to help you keep track of your cup!

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 5 equally-sized pieces.  If you've mixed two packets of Sugru to make a new color, divide it up into 10 pieces!

Step 4: Shape the Sugru

To make it easier for forming around the cup's lip, shape the Sugru into a little "nugget" or short worm.

Step 5: Form the Sugru

Mold the Sugru nugget over the edge of the cup.

Step 6: Stamp the Sugru and Let It Cure

Mark the Sugru with the end of a coffee stirrer with your initial, then, make 4 more!

Wait 12 hours, and it's ready to go!
