Pedal Powered Tennis Ball Launcher - Innovate or Die

[ketamphetamine]

imagine putting your dick n balls in that thing, think of the chaffing... ouchh

[Torabayashi]

Why not just play tennis with the person on the machine...

[lureyourkidsinvan]

That is sad.

[WeaponSamurai]

One Problem.

Zombies.

[ajpreteau]

this is genius and wow it's also green ur amazing, and no I'm not trying to be sarcastic I think this is great

[bu99yb34r]

to much time on ur friends

[1scifreak]

You might as well us a racket!

[TrippyTech]

If i want to make something simmalr may i?

could u provide me iwth parts and how to guide!@! :D

THX

[Lethalis1234]

that is genius

[zeoliveira22]

That's sweat :DD

[nirvanarock93]

great design!

[Puna1030]

How does it drop one ball at a time?

[botisto1]

i would just like to say why? isn't it a bit easier to just rally with someone else? the whole point of a tennis ball machine is to be able to practice by yourself. smart design though. im currently making a more conventional electric one from scooters from the tip

[Doberboy218]

Cool two people can get a workout at once! I advise thinking about putting a windshield apparatus on the bike then getting a patent!

[Farran5productions]

Freakin awsome!

[captainmorganhook]

MacGyver! LOL

It work fine, as long as you don't hit the guy on the bike!

[yamahabansheerider]

NOW catch the balls on fire!

[ZeDuBreju]

Very criative and it works good! I've made a table tennis ball launcher, but I used motors.

[PoftheBR]

huh huh, Bevis she said bike skewer

[anthro81]

so how much is this going for?

[newcomer9747]

wouldn't it apply a backspin on the ball. perhaps you could fashion it such that it is able to apply top and side spin as well.

[don4of4]

That is so cool!!!!!!

[janovewaldner1]

Congratulations, I admire your enthusiasm!

[fatpeepsRfunny]

it would be hilarious if the guy on the bike got nailed in the face with the return hit :D

[bteeuwen]

i really like this one, works better then i expected.

[zdepth]

erm... which wheel is launching to ball? top & bottom together? so what spin is the device generating? top or under?

[dbrctennis]

well, frankly, it looks awesome at first. But after seeing how it works for a while, i wonder if getting a hitting partner would be easier. Besides, i think the workout on this ball machine may probably exceed actually hitting some balls. But, appreciate your creativity though.

[523778]

sick

[choochootran]

this is AWESOME. I'd want to make one or buy one.

[ilikepieinmyshoe]

yeah i agree you should put the plans up

[jumbochicken1117]

What did you need to make it?

can i have the plans to?

[ilikepieinmyshoe]

give me the plans for that

[RafaeINadal]

or you could get of your bike and get a racquet and hit the ball to your buddy, kind of pointless idea but funny to watch.

[dynamicwolf]

that is awesome

[tennis2nuby]

nice invention!

[Julieanniscool]

cool, I need one of those :]

[CaeserOct]

Wow, this is exercise for two people: one to hit the ball and one to pedal the bike. Amazing and green idea!

[jakery137]

why would you use it for tennis shoot people with it stupid!!!!

[colcheeda]

very good how long did it take to make?

[456run]

that is sooo cool, xs good...

[Partspare]

You almost had something here. It needs to enable ONE person to be able to practice tennis returns by themselves.

[centry96]

does he have to wear a helmet whileon a bike that isnt moving........

[Correlianum]

@centry96

Helmets commonly act as protection for the head.

Also against tennis balls, as scientists have proven with newest studies!

[SlickJuggling]

do you really need to wear a helmet while on a stationary bike?

[crazypyro424]

I hate tennis but that is simply amazing/ awesome.

[eggchaser7]

that's simply delicious...

[AlFleissig]

its still clean you idiot. I think its really clever too.

[sn1pe352]

I'm sorry , but if this is supossed to be a "clean" solution. Its truly retarded lol

you could just get a friend to throw the ball at you instead of hiring a slave to ride a bike all day :]

[01deerkiller01]

lol

[TyaxComp]

So cool,,

[hellomynameistigi]

genious...

I have seen too many bikes being put on the side of the road from wasteful suburbia rednecks, but this video has proven how recycling otherwise unneeded bike parts can pave way for a prosperous gadget that does not need electricity. It can also be a weight loss program superior to weight watchers.

[mylarjorgen]

Nice bit of engineering, but why does the bike rider not just bring a tennis racket instead.^.^

[BlackShiraya]

ideas very cool. woulda been funny if u get hit and got that on video then put a warning "Pedalers should be careful and waer face protection"

[yoshimiso]

Why is he wearing a helmet on a stationary bike???

[alastairthegreat]

presumably, in case one of the balls comes straight back

[pedalpoweredtennis]

Just didn't take it off, because I had rode the bike to the court for those shots. I should have been wearing my full face helmet. I haven't been hit yet, but all a matter of time.

[seivren]

Umm... Since the pedaler is right beside the tube isn't it possible to aim the ball at yourself by accident?

[AlexBlueberryman]

This is a very intelligent invention, but not very practical. But very nice

[juicycle]

mmmm very exotic thought. neatly chisled. - w

[pedalpoweredtennis]

An additional feature which we did not have enough time to add before the deadline, but will be adding in the future, is an airtight tennis ball storage container which can be pressurized using an onboard compressor that flips up under the bike wheel. When you are finished practicing tennis, load up all the balls into the airtight container, flip the compressor under the tire, and pedal. The container will pressurize to about 14psi, which makes the balls last longer, resulting in less waste.

[fossilfool]

Reminds me of a prop in a Jean-Pierre Jeunet movie. Liked the piano music. Looks fun at night.

[ckflanagan]

neat idea.. i could use one of these
