Cathal Garvey in Cork, Ireland, developed this 3D printable centrifuge attachment for a rotary tool, dubbing it the “Dremelfuge.” What an awesome alternative to an expensive piece of lab equipment, congrats on paving the way for DIY science! If you don’t have access to a 3D printer to print your own, he’s made it available for purchase on Shapeways, where it’s still cheaper than a traditional centrifuge. [via @bre]

    Can someone explain the bit about the water leaking out of the containers? I am assuming the centrifugal force is creating a low pressure in the tube due to compression of the fluid thus some of the surface liquid is traveling towards the center of rotation to achieve equilibrium and eventually out of the tube. If so, why do both tubes not experience this behaviour? Perhaps the seals on the tube caps vary?

      Replay the video again but this time listen to what he is saying. He explains that the tube is damaged from a previous experiment.

        Yeah, I took a closer listen after my first post. I did post a “nevermind” right after that but I guess it didn’t go through for some reason.

    You’ll put your eye out, kid.

    Neat piece, Very similar to Sean Ragan’s post on the 23rd.

    :) I couldn’t imagine where else but MAKEzine I would have heard about it,but I was familiar with this product.

    So I did the on-site google search and there it was.
