Sam and Si catch up with Dr Kei Takashina at the University of Bath to explain the science behind the astonishing bouncing droplets, and the boys set a challenge for you to try at home with everyday water droplets.
If you're struggling to balance a droplet on the surface of water, why not try adding a bit of soap to the mix.
Special thanks to Dr Kei Takashina, Maria Chan and Fiona Bunting from the University of Bath.
