Would You Care For A Compact Personal Genome Sequencer?


I wouldn’t have thought that so many BBs could come out of a bit of DIY like that, but you can’t argue with that ruined apple. The secret is (apparently) having a one-way valve so that the BBs can travel towards the chamber but not away from it.

There has to be a better way of introducing the BBs than blowing into the tube, though. If you’ve got your mouth on that thing and the valve goes, you’re going to get a BB sandwich before you can say “oh god no!”
