Instructables is sending us free Sugru to play with! This stuff is basically playdough that hardens into silicone rubber overnight. So you can create new 'rubber' parts, replace/repair plastic stuff.
Some things you can do with it: mold to your phone or camera to make it drop-resistant, make a mold of an object for casting, line your shoe to prevent blisters, replace your broken-off crockpot knob or eyeglass noserest, stick to a metal pot handle as an insulator, turn an old book into an iPad case, etc.
The Instructables website sends out stuff to hackerspaces/makerspaces so we can make things and post tutorials. That's a nice thing for us and for them.
This will be on an off-week from ShowNTell.
And it's free!
