I am a high lecture physics teacher and I purchased one of these for my lab. It works very well. There is now one other assess that indicates that there were no directions with it. I can't retract if I got any directions, but honestly, they actually aren't de rigueur. If you be with you the ballistic pendulum (and I don't know why you'd be shopping for one if you didn't), it's a very unadorned contrivance. And after comparing prices for a while, I place of safeguard't found any that are a best deal.I urge this, and I'll probably be buying more in the future. - Nathan Smith "euler010"
Most of the instructions are missing. I reflect I got each additional leaf from a very poor copy apparatus. I would restore the business if I had the calculate.I have cultured from this and a very crappy gyroscope with the intention of scientific apparatus through in Plates are not worth a dime. Skip this business. It's a dissipate of time.

American Educational Ballistic Pendulum Apparatus, 16-1/2" Length x 14" Width x 15" Height
Shock pendulum apparatus. Exceptional for demonstrating the law of conservation of momentum and trajectory, the unit uses a nylon pendulum with a tapered rubber slot in. Both pendulum and base have leveling screws. The jump-biased gun has a self-locking trigger and rubber shock absorber to prevent damage on impact. The scale is manifest in degrees and is registered by a counterweighted needle that remains in house at the height of the arc. Directions provided. Events 16-1/2" length by 14" width by 15" height.
