The SealBot - Spillproof your cup.
http://www.thesealbot.com/
Smaller than a coffeemaker, SealBot is the only consumer appliance that will create an airtight seal around your cup that will not break, so you can transport food/drink without worrying about spills. Throw it in your purse, gym bag, passenger seat, etc. It won't break.
Seal. Use. Recycle. Repeat.
