Etsy Wednesday is back! It’s a Wednesday where I feature a science-themed item from Etsy. It ran irregularly on two previous locations of the blog, and you should be able to find some in the archives. I stopped because I got to the point where I had featured all my favourites, but new things have gone up in the mean time.

What better way to celebrate the return of Etsy Wednesday than with party hats?

These science party hats are part of a full science-themed party package from Mary Had a Little Party. Life in general is a science-themed party, so you might just as well buy these and wear them all the time.
