what would be some good inexpensive orbs that would work for cannon shells (i will be building a cannon this summer and i think golf balls would burn up to much and i think marbles would break ball bearing would work but i want to have sothing at least 6 inches in diamater

I would have two large, EXTREMELY LARGE balls attached with a rather large string or steel cable or whathaveya. I would throw one ball in space and BAM it goes on forever!\n\n~or two quote someone, until it hits something.

elements new helium boards are good. i have 1  and they are better then regular boards, they give you more balance when your grinding on rails

My husband is a 13B.  He doesn't get to shoot much anymore these days, but enjoys being a red leg through and through.  I love being an artillery spouse.  When he was deployed to Iraq I got a tattoo of a heart with cross cannon in the front and his name. It totally blew him away. All of his buddies in his unit thought that was the coolest thing. Can you get more red leg than that? When we go to our St Barbara's balls, we can't wait for the Artillery Punch, that is always the absolute best part of the evening.

My science class did the same project a few years ago. I suggest suspending the egg within a sphere, try making wings to slow its fall. I dont think whether it is a trianlge or not will really affect its streght to much. Good luck

i had a amf gold angle but i have moved and lost it some where in the move so i need a new boling ball and th hammer brand is one of the finest bowling balls i have ever seen so i will check this one out.why i like hammers becouse if you look at it the out side shell is a lot thicker than any other ball on the market. as when i bowled on leagues a friend of mine had one and its shell was at least twice as thick as the one i was useing so i do not think you can go wrong with a hammer just make sure you get it drilled by a pro and you shall be happy and geting personal bests and go ahead and raise you avrage.

My dad helped me do the solar system in a big cardboard box, with fishing line, styrofoam balls, paint and construction paper. Inexpensive and I got an A+++++!!! We hung the styrofoam planets from the top of the inside of the box after we painted them and decorated the inside of the box with a black background and it was cool! bradnmich@bellsouth.net

Oscar. You have written too much. This 125m tower stuff does not matter compared to r=6.38*10^6. Why is this talk about 1.00 km and angle theta? See what “zipper” above says. Besides I answer your last question << Why is the trajectory of the cannonball not parabolic?>>. Why should it be if both you and Newton demand it to be circular? Assume that V1 of cannonball is the 1st cosmic speed corresponding to a circular track. Let V2 be > than V1, then you receive an oval track. Take V3 > than V2, then the track may become parabolic, so that cannonball would never return back to the cannon to linger out among planets and stars. If you are intrigued calculate a set of velocities and corresponding orbits of the cannonball. If cannon is not available consider a football! I like your inventive wits – to be honest!

get a tippmann 98 custom.  it it tourny grade right out of the box a,d you can customize it like heck and still have it ending up costing as much as one of theose autocockers.  i have one and ive got a flatline and a stock on it and i get superb performance out of that and the whole thing cost me around 250 after stock and barrel were added on.  the gun itself comes with a kit and costs around 170.  also they just came out with a loading system that is the same as the a5 so now its able to load the balls faster.  it is also a great gun because you can bang it against stuff and you wont break it in any way.  thats the one i recommend

With all due respect to bobo, guns fire just fine underwater - just make sure the entire barrel is flooded with water and that your bullets aren't hollowpoint so they don't expand in the barrel.\n\nDoing that will really screw up your gun, but the cartridge will fire unless it has water inside. Metallic cartridges make their own oxygen as they combust; they'd work just fine in outer space minus the loud noise.

Good barrel, what type of paintball are you playing by the way? That would help a bunch.

the best beginner guns on the market are the tippmann 98 custom the custom pro, and the A-5 you can literally bang them against a brick wall and they will still work lie they came out of the box. a big bonus is that you can customize these guns to fit your style of play as you get more experienced. you can put on sniper barrels, drop in just about anything that will make you shoot faster, you can put on nitrogen without having to replace any parts, and so much more plus tippmann just came out with a new anti chop system for these guns so that means if a paintball gets stuck you can still shoot without having to clean your barrel. another thing is that you can field strip it and fix the gun if it malfunctions during a game. tippmann has made great strides in producing reliable, dependable, and cheap markers. i would recommend them to anyone even to people who have been playing longer than i have

If i were you i would try to make one... think potatoe gun, and grappling hook... if you want something quiter i would think about a crossbow+grappling hook...

Yes, the discover channel show myth busters actually did a show on this once after someone asked the same question because they watched a cannon ball bounce in a war movie.  Cannon balls are very heavy...so if they hit a soft or low density surface like dirt or grass they will generally make a divet and come to rest where they land.  However, if shot from a low trajectory they CAN skip...like skipping rocks on a lake...in fact if shot at a fast enough speed they can even skip ON a lake themself.  When dropped from ontop of the myth busters studio building the cannon ball hit the concrete, did some major damage that made Jamie really mad and rolled off the sidewalk BUT fascinatingly enough...slow frame film showed, afterward, that when the cannon ball rolled off the sidewalk it actually bounced once...a tiny tiny bit.  They also did some research with revolutionary and civil war historians and found that a VAST majority of cannon ball injuries from that era actually CAME from low flying cannon balls taking off legs and such just like in the movie.  In fact the true myth wasn't the bouncing of cannon balls...it was the big explosion of dirt and shrapnel that fly out and take down 15 guys around it.  Cannon balls dont break up when they land like grenades and bombs...so that doesn't really happen.  Sometimes if the ground is soft enough there will be a big dust cloud but unless the ground is covered in nails and scrap metal...there won't be any shrapnel in the dust cloud to cause damage.  Most of the time, though, the ground was uncultivated so it was generally hard enough that a cannon ball landed with a thud and stayed there.  According to the experts there were even opportunities after a battle for the winning side to go out and gather up all the expended canon balls off the field and re-use them.  The single greatest danger from cannon balls at that time was actually the low flying bouncing ones that skipped over the ground and ripped legs off as it went...(by the way in the scene in The Patriot where it bounced high enough to take the guys head off...that was busted.  They're too dense to actually BOUNCE like that...they more or less SKIP which is still a form of bouncing but most injuries were leg injuries NOT decapitation by cannon ball)...there was a low chance of a cannon ball landing directly on a person but the odds were outstanding...I can't recall the actual numbers now but I know when I watched it...my jaw dropped.
