How to make (or where to buy) spring loaded fins for a model rocket? Answered

I think it would look really cool if I could launch model rockets from some sort of tube or underground silo. The only problem is that the fins get in the way of securely packing the rocket in the tube. I would like to know if there are plans for spring loaded fins or if there is a place where I could buy a set of spring loaded fins.

Need advice on making a proposed rocket I've devised different to the ones seen on here, before I waste materials?

I was thinking of making a rocket and using the fuses in a party popper as the propulsion, I was going to set up 4 gutted poppers with just the fuses on a 600ml/1 or 2 lt bottle and use a string fuse attached to the popper fuses at equal distrance running into a centre fuse/string to light it and get clear.I would use skewers or something to make it launch straight up.I would have the bottom of the popper housing/film cannister against the ground/launch pad. Has anyone tried this? Would the popper/poppers just simply blow up the thing I put them in and not work? Would I be better of doing the film cannister cannon thing instead of poppers.?

Water Rocket Launchers

Water rockets are fairly new to water warrior technology. To reduce our carbon footprint, water rockets are built using plastic bottles. This forum topic talks about the operation of standard water rockets and launchers, how they can be used in a water war, construction of water rocket launchers, rockets, and add-ons like water balloons on the tips of rockets, ammo clips, and grips as well.
