Interesting thought created by Ultraspire, a reusable and collapsible plastic cup for marathon and ultra trail races in an attempt to save waste. Might have great application for some of us as the size and weight are quite small and it can serve as a drinking vessel and water scoop among other things.
As per the UA website:
