Make drinking easy for disabled users
The idea for this came to me when I saw my Granny trying to drink from a glass. She has very limited mobility, even in her hands and fingers and it takes her a long time to do anything, and she kept having trouble with the straw in her drinks moving around in glasses or sometimes just falling out.
It only took a small amount of sugru to form this around a normal glass and it seems to work pretty great. It can be removed and fits on most cups and glasses. I'm going to try making one with flexible wire underneath to help it hold its shape and grip even better. By @solarmechanic, via sugru gurus (bit.ly/NMcMxj)
