From Huff Po:
Bottoms up, literally.
A company called Red5 has made an upside down wine glass in which you can sip your Malbec from the foot of the glass rather than the lip for the bargain price of $10.
“We don’t mean to be rude but we bet that your glass cupboard is pretty boring,” the gadget company wrote on its website. “Lots of standard glasses in the standard shape that you would expect to find in any home. The Upside Down Wine Glass is a revolution in glass design and will literally turn the world upside down.”
