Please don't be as cheesy as this when doing school visits. It just puts off the students.

Honestly.

It isn't making them laugh or getting them interested or even making them subconsiously remember the science.

It just annoys them.

They stop because of that little friction on top of the rope and because of that little air force and energy transformed into heat inside the balls.......

I think this a better example of Newton's 2nd law rather than 3rd. A rocket or jet engine is a better example of 3rd.

I like this toy, try this: avoid the center ball move, put for example a magnet below without touching it, and then repeat the experiment and observe.

this way does not swing so much. and it is much hypnotic

i second thehaz666

[stirlingsteamboy08]

do they stop after a bit i thouht that they keep going

[oakberry61woohalol]

Newton cradles were invented by sir issac newton when he discoverd about stop and motion that means something can't stop once it's been set off.

i cudnt hear it, and it made me kringe all the way through, but was interesting.
