Just use a motorized paddle and then that will catapult it into the goal

or you could make that hotwheels part that shoots cars waterproof and a bit wider. (more acurate)

that is too difficult

sorry i didnt mean make...i moddified mine to shoot bouncy balls...only about 2meters tho  lol but ping pong balls are lighter.

lighter isnt always better.

take a lightly crumpled up piece pf paper and throw it.

and the same piece densely packed. the small dense piece will fly farther, faster and more acurate


trust me. i do it at school

ya i know. i usally put a weight at the back of things i throw in class. anyway nuf talk of this. (off topic)

i didnt understand what type of mechanism r u telling plz  specify it clearly guys coz iam noob here

[SmAsH]

well two wheels spinning opposite ways something goes through middle touches both wheels and gets pushed through fasssst. the other is just paddles stuck into a cork or something and it spins and the paddle hits the balls (not very accurate tho) usially shoots it up or straight down.

Imagine that spinning and imagine a ping pong ball inside it -- the ping pong ball would fly!

but not accuratly

but not accuratly

well if the paddles were thinner , then it would be accurate

small enough compartments for the ping pong ball to slip in and not move around
