Cool, I made something similar to that using a bicycle pump and mine wasn't four bar either.

More air pressure built up = harder,faster thrust!!!!

[TeddyMadison]

Nice. I'm glad you had your dad step in. Before that, I thought the prop was 3ft tall when not extended lol.

[mompood]

[lolgurlyyy]

Where do you get the pneumatic system?

[badunclemark]

20" pneumatic cylinder and 3 way solenoid valve won off ebay.

[PDALEguardmember]

@badunclemark you could also make one by using a cheap basket ball pump and an air compresser

[themagiccoasterlover]

how is it a four bar pnematic pop up?

[ComPrt3]

I'd really like to see how that was made, or atleast get a look under the hood.

[CrunchieDan]

That's huge. Just need to make it go up faster, and keep the area around it dark and use a strobe light.

[marcussatu]

haha i thought that thing was like 2inches tall til that guy came in and stood next to it...but u should make it have some more force so it pops up faster

[houseofbaddreams]

having yur dad step in made a big difrence in the forced prespective of the prop. It looked as if it were only 4 foot tall untill you had him do that.

[xabaras]

your dad doesn't look too scared
