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 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.

I recently re-discovered this box of model rocket engines in an ammo can in my garage. They look to be in great condition. I don't have any of my model rockets, or any parts to build them. I'm really wondering if there is something else interesting I could do with these. Also, they are at least 20 years old. Prolly still good, right? :/

when making a rocket engine do you need to use pure kno3(potassium nitrate) or will any stump remover do? Answered
I need max thrust witch is why I'm asking,and if you know of an even more powerful engine mix be it liquid or solid please do tell.

I am making a rocket out of a refridgerator box for VBS. I will be spray painting it silver/grey, and it will have a door to enter it. Does anyone know what I can put on the rocket (windows, control panels, nuts and bolts, etc.) that will make it more space-like?

I am looking for the math equation that converts G load to speed using Arduino (https://www.adafruit.com/products/2796)? I am building a high power rocket data logger/controller. I need to know the speed by using accelerate of the bird. Yes I might be able to use GPS info, but at super sonic speed GPS can not keep track of the speed. The bird is a 2 stage bird. I want to stage when about 40% of the speed has bleed off. Thanks Rocket Nut

I'm going to join two 1.25 litre bottles together for a 80 psi water rocket. Is it ok or should i make it more longer with a third bottle? what should be the ideal volume of the bottle for good efficiency at 80 psi?
