And after you’ve watched that, here’s that Bearded Science Guy Instant Cloud in a Bottle video that she features.

Watch these next: Kari Byron makes a cloud in a bottle, which includes a slightly easier version of the experiment, how to build your own particle detector, and how to identify clouds.
