Inspiration

Using a water rocket to get a lifeline to a drowning person.

What it does?

It is a water rocket with a handheld launcher that propels a life line to a considerable distance. It can potentially save the life of someone who has fallen into the water - off a boat, or from the rocks, or who is caught in a rip, or someone being swept away by flood waters.

How I built it

We used Blender and 3D printing to construct the part. The rocket nozzle and release mechanism was constructed from hose fittings.

Challenges I ran into

Getting the rocket aero-dynamics right too some experimentation. The release trigger mechanism also took a bit of trial and error to get right.

Accomplishments that I'm proud of

Original idea. Designed and built from stretch in two days at Hackagong.

What's next for Rocket Line

We are already working in RocketLine Mark II - bigger and better!
