Vacuum Packing Parachutes!?

We took Martlet 3 to Scotland for a test launch in summer 2016. Due to a late minute design change we could not get the parachutes to fit inside the booster section of Martlet 3. Perhaps inspired by his PhD on Dyson vacuum cleaners Jack suggested that vacuum bags might help, no one thought it would work. A short trip to ASDA and some experimentation later and the chutes were in the rocket. What's more they could be pulled out with negligible force! The technique involves fitting the parachute bay and parachute (in it's deployment bag) inside a large vacuum bag. The vacuum then assists the packing of the chute into the bay. We were stunned how effective a technique it was for packing parachutes.
