OK, great LSU parents, time to walk the walk. A little hands on MATH PROJECT for you and your kids. Yeah, it has a little trig, but me and Sal Khan have taken care of it for you. The only problem is lack of purple and gold paint. But you guys can fix that. Ok, We are gonna show you how to build something with your kids, and then use MATH to aim and launch ping pong balls, crawfish, or even a boudin ball into grandpa's mouth. Remember the purple and gold paint. First Video: How to build the launcher. (This is not a jackleg POS, either): https://www.khanacademy.org/science...le_launcher/v/build-a-ping-pong-ball-launcher Next a little math with a little trig, showing your kids (I am sure you remember trig) how you could figure out, how far it will shoot! Even if your kids are middle school, the math should be a snap. If you can figure out initial m/s velocity, you can do some pretty accurate shooting. This video is more of the CONCEPT. But you can figure initial velocity out, if you take a bunch of measurements, but your kids, would rather, I am certain, just lock, load, and fire! https://www.khanacademy.org/science...ional-projectile-mot/v/projectile-at-an-angle I am going to, I think, assemble the parts to make six of these. Since it is math class, I am going to make students figure out how best to approximate the initial velocity, as well, once we get back to school, after spring break. Give it a try...but you need a lot of tools!
