Re: Momentum Demo

I also use one regular Dr. Pepper can and one diet. The diet can goes half
the distance as the regular (the diet can I stuff with enough paper to make
it twice the mass of the regular can. Good stuff. The lady finger is weak
enough to just send them to opposite sides of the room.

Safety considerations would make me avoid this.

A 'LadyFinger' is quite adequate, behind a blast shield of course.

back in the mid '80's or so, you could select either Al or steel cans
for interesting comparisons.

One aluminum + one steel let you measure the different ranges and
work back to the mass ratio.
