Researchers at ASU Build a Jetpack to Make People Run Faster

MINI BELIEVE IT OR NOT –

Researchers at Arizona State University created a jetpack that doesn’t fly. Instead, it straps onto a runner’s back and helps them run faster.

The idea behind the jetpack is that every soldier should be able to run a four-minute mile
Jason Kerestes came up with the idea for his 4MM (4 Minute Mile) project
The pack features two dual jet thrusters that face behind the runner to propel them forward
It generates continuous thrust to help runners move faster while reducing their metabolic energy expenditures
It was found to make runners faster, but because it was so heavy, any benefits were negated



MINI BION
“BIONs” – short for Believe It or Not – is the word we use at Ripley’s to refer to anything that is unbelievable and worthy to become part of Ripley’s lore and collection.
