Richard and the team explore one of the biggest mysteries of air travel. No, not how fast does a jumbo jet need to travel to produce enough lift for take-off. Something much more important than that - will a cup of water spill over a passenger during a loop-the-loop? Richard has no intention of risking getting wet himself, so undertaking the experiment at his top-secret testing base is one of his ever-present, and ever-expendable, Lab Rats. Will the Lab Rat get a good soaking or will good old centrifugal force save the day? Meanwhile, back in the lab, Troublesome Trio and Science Smarties take part in a brand-new sport invented by Richard - Bungee Shoot Out, which is an ingenious mix of football and kinetic energy. The teams have to get as many balls in the net using a bungee launcher as possible. But the ever-energetic Ninja Nan is goalie and has help from her garden gnomes. Finally, Richard's potential replacements for the Lab Rats return for the Messy Messy Mess Test. The Snot Bots are still not quite working, though, and the two teams must feed them the most potent medicine available to Lab Rats - prize discs.
