EISCO Catapult Kit - Build Yourself - STEM Learning - Comes Explore Force, Acceleration, Center of Mass, Hooke's Law & More - Garage Physics

Bought this for my 5 year old grandson and he loved it! Easy to assemble and has features that allow the distance and angle of trajectory to be altered. The throwing arm has a large hole in the end allowing a ping pong ball to be seated in it while preparing the catapult for firing.. We added a wooden disc underneath this with a smaller hole so that other size balls could be used. With this modification, we've successfully attacked many wooden block castles using bouncy balls for ammunition!

Arms broken on all three catapults within minutes of each other. We only had two rubber bands. Very disappointing. The arms were built out of particle board

I bought this to use in a class I am teaching in Lean six-sigma, (a manufacturing improvement process made popular by Jack Welch in GE many years ago), and it works well. It is easily adjustable so the adult students can collect data and study improvements. Seems like it will hold up well.

Looks like a nice design and well made but there are no directions for assembly!! Easy enough to figure out from the picture but they would have been nice.

This kit was so fun and easy to put together. My 7 year old had a blast helping put it together and playing with it. I love that it actually comes from a small company and not some huge corporation.I think when the 2nd born gets a little older I’ll have to buy another.

My dad loves it

Very cheaply made. Pressed particle wood. Broken the very first time it was fired. STAY AWAY JUNK!!!

This item worked well and we would purchase again. It was used for a high-school physics. The only area for improvement was that during assembly a small amount of sanding was required on the side pieces to get them to fit optimally.
