A flea can outperform the Space Shuttle in terms of acceleration.
In a moment, a leaping flea may reach astonishing heights of roughly eight centimetres (three inches). Acceleration is the change in speed of an item over time, which is commonly measured in 'g's, with one g equaling the acceleration generated by gravity on Earth (9.8 metres/32.2 feet per square second). Fleas are subjected to 100 g, but the Space Shuttle is only subjected to 5 g. A flexible rubber-like protein in the flea's secret lets it to store and release energy like a spring.
