A Community of Halloween Prop Builders

OK so I'm working on a jack-in-the-box
General info:
Jack: Store bought 12' jack
Lift: This is where I need some Ideas.

Initial 10 ft unistrut channel for the rise rail
Home built shuttle

What I need is a way to rapidly accelerate the shuttle from the bottom of the rail to the top
I'm thinking a retractable clothsline assembly.for the uplift puller

pnumatics are an optoin, but I'd need to fabricate something that could lift ~8 lbs anout 10 feet up very fast

Thoughts ?

I keep itching to make a scissor mech, so I vote pneumatic with scissor mech.
