Feeling hot? Summer melting your cool? Well have no fear!
The designers over at Mathery have come up with a simple solution to cool you down:
The duo just froze a portion of chain in each ice cube section and voila!
It might not work for every day, but it's perfect for hiking or a day at the beach.
Designers Erika Zorzi and Matteo Sangalli started the blog project in 2010 while they were in design school.
They created more than 100 simple, genius inventions, like this oven that uses the heat of your computer.
And this backpack made from a recycled grocery bag.
And this rain hood made from a plastic folder, for when you forget your umbrella.
