So this is what an assay for locomotive ability looks like. I'm a bit more careful with them when doing the actual experiment but you should try filming with one hand a whacking flies to the bottom of a tube with the other (I can see that sentence being misquoted).
For added benefit check out the sound effects. That weird drone is the sound of the carbon dioxide being pumped out to keep the flies unconscious (and probably myself soporific). The really unpleasant sound is Radio 1 playing in the background - possibly the cruelest thing the flies are subjected to.
Now I need to edit it so that it looks semi-professional in my presentation. The moving pictures may distract the audience from the less than stellar results.
Don't worry, I'd never try and submit that as supplementary data in a paper.
