Some horrible camera work... probably a cell phone. But a very good experiment for high school science.

I remember doing an experiment for high-school physics, where our teacher challenged us to hit him with water balloons with one of those 2 person slingshots. He had figured out the trajectory equations so that he would be just out of reach.

The same professor did one where you stand on a chair and have a bowling ball hung from the ceiling held just up to your nose. Because of conservation of energy and the added friction of the rope, it wouldn't come back and hit you in the face.

holy damn! she's a better man than me. I wouldve cried like a 10 year old girl after my face just exploded bowling ball sized produce

Huh. I had always wondered what the inside of a bowling ball looked like, and now I know.

Damn, I really thought she was going to get a bowling ball to the back of the head! ....maybe next time.

Since we're on the subject, this page show the supposed scale of an atom, and how insignificant the electron is in size, and yet their electrical forces are equal.

The universe into bowling ball size was actually interesting. Obviously false, but space between particles is a pretty cool concept. Mostly seen in stars. Neutron stars blow my mind.

It's probably not far off, the whole of humanity could fit into the volume of a sugar cube if all empty space was removed, so the universe is going to shrink in similar amounts.

Argh... you're missing the point. It's not saying you CAN or COULD, it's merely highlighting how much of everything around us is actually empty space, it's a handy concept to get across things. I'm not saying you COULD compress the human race into a sugar cube, I'm saying that for all our 'size', most of us is nothing physical.

This does not in any way validate a word these charlatans are saying re homoeopathy... it's just a statement about the nature of things.

ignoring the fact that it's physically impossible to do, it's also mathesomethingly impossible because you can't collapse electrons like that since electrons don't have a fixed physical boundary. they are more like a moving clump of fog with no exact border.

It's the 2010 Doritos world "toss-your balls" bowling ball throwing semi-finals. I missed the championship round last year when a concrete truck took out the power line to my trailer last August


I'm not sure if you just made that up or not, but it's hilarious either way.

No.

Balls.

Thank you university mathematics >> ^MaxWilder:

"Ball" does not mean "sphere". Balls can be spherical or ovoid, solid or hollow, or even have holes in them (bowling ball, wiffle ball). You can have a ball of wax that is any shape you want.
In sports, balls are spherical when you want a consistent movement, or some other shape when you want unpredictable movement.

hahaha all of you couch physicists. Yea, the only force acting on the bullet in the "y" component is gravity. It's the same for both bullets. In fact the acceleration due to gravity is the same for a bullet and a bowling ball or a semi-truck and a feather (in a vacuum of course).

Now the spin of the bullet, while stabilizing the bullets trajectory in the "x" direction, has very little affect over the bullets fall. That's probably a little more difficult to understand. Would probably need a course in fluids and aerodynamics to solve that.

The harder thing to understand would be if I told you that if you fired a bullet from a rooftop straight down to the ground, or you fired it at an upward angle, due to the conservation of energy, both bullets would have to be travelling at the same velocity magnitude when they hit the ground (although direction at impact would be different, obviously).
