Remote control opening box...

[Russinating]

I'm looking for something that's basically a remotely operated opening box, the usage being to drop some confetti/ticker tape. It can look like anything, it could be a toy or whatever, just not expensive.

Any ideas? :/

This for your multirotor?

Yeah, groomsman at a wedding in July, thought it'd be a cool surprise!

I've not used servos since my teens, how much torque would I need to pop open say a metal hinged tin? Would 2.7kg with something like this do/be overkill/not be enough? http://www.hobbyking.co.uk/hobbykin..._Servo_2_7kg_12_5g_0_13sec_UK_Warehouse_.html
