So I heard that next year for a physics project we would have to:
Make a contraption that could launch a water balloon far!

So this got me, and my best friend, thinking...

smiles rose on both of our faces...

Now I know what you all are thinking, "You guys don't even know if that's going to be the actual project next year!" and "Ha good luck with that kid."

Before you all start hating...

1) My best friend and I are going to build the rail gun regardless of a possible future physics project.

2) We both know how to build one, not hard at all and we know the supplies required.

3) I know I'm asking a tech site, but I know one of you guys have thought of/attempted building a rail gun.

4) And no, we don't plan on taking over the world with it anytime soon


My question:

We are both going to contribute $75 (And possibly more if we get supporters/family members on our side). With the current $150 limit, could we...



Now before you try to shatter our dreams by saying no without evidence. We are thinking of a cost efficient device, not just a build with the best possible material, other-wise we would lose the money in a second. We thought about it and have come up with a good plan for building one under budget.

We are just looking for personal opinions on once we come up with a final layout on how we will put it together, that it will be able to compete with others projects. We are determined to do it, but experiences of others may guide us to avoid making an error that will reduce the potential outcome of our final project. Tips and helpful suggestions wanted!!(No harsh comments please ! We are curious and reaching out to ask for your opinions!)

Also, we know copper is the most conductive but it's expensive, so we've resorted to aluminum! (And our high school I believe has a metal works class so we are going to attempt to see if they could maybe help us with our project?)
