#1508: StabiLIDy

I watched a woman knock over a cup of coffee whilst traveling by train today.

Today’s invention would have helped avoid such a small-scale disaster.

It is a coffee cup lid with a depression in the top. Take off the top and press the cup into the depression until an interference fit is achieved.

This forms a drip tray/saucer as well as a base which maintains stability -even when the level of coffee remaining is low.
