Yes, the video feels a bit like a Portlandia sketch waiting to be written, but that doesn't make Cuppow any less ingenious.
The Cuppow takes the place of a flat metal lid and is secured by the jar's screw-on ring. Shaped like the usual disposable coffee lid, it is BPA-free, recyclable and costs much less than a new travel mug. Pair it with a heat-resistant, inexpensive, wide-mouth canning jar — and perhaps a cozy to protect your hands from the hot glass — and you have a smart commuter cup that is sure to be a conversation-starter.

What do you think? Would you use a canning jar as a travel mug?
