this is the archimedes scale, by federica castagno and sara petrucci. such a simple design, this is just the kind of thing i need. it doesn’t take up much space, it can be used as a bowl as well as scales, and i can’t see why it wouldn’t function great too! using the principle of buoyancy in the water, the bowl indicates what weight is inside it by how much it sinks. the only downside i can possibly imagine is having to fill up your sink or an even larger bowl with water.

these are the ‘gravity ruler’ luggage scales, by politecnico di milano students marcella maltese and lin wei. you wonder why no one did it before. for me, it’s another one of those ‘i had that idea a few years ago’ kind of designs. not to take anything away from it though, this is such a good design; so simple and so effective. the packaging is great too!

from the original article:

The demand for these things (what with the miserly 15kg allowance on Ryanair flights in Europe and the clumsiness of other similar products) was proven when the pair sold their first batch of 35 in under an hour at the Travel Trading fair in Milan. They’re now looking for a manufacturer.
