Spitballs

ZZ

468 views

So the other day at lunch when a couple of us were spitballing ideas for blogs, I figured what's better topic than spitballing itself. To test the physics of this I took a straw from the lunchroom and a smaller one from a different chocolate milk container of mine, with a similar radius. I blew projectiles (not at anyone) and found that the larger straw sent them further and faster than the shorter one. This is most likely because the longer the force I exerted on the spitball was, the larger the impulse (change in momentum) it would feel. The longer a force is applied on an object, the faster it will go and therefore the farther it will travel. It's amazing how in even the most primal of children behaviors physics can be involved.
