Newtons cradle Memes

Give a physics teacher playground duty and you've basically created a living Newton's Cradle experiment! The poor teacher can't help but see those swinging kids as perfect demonstrations of conservation of momentum and energy transfer. Next thing you know, they're timing the oscillations and calculating the potential energy at maximum height instead of watching for scraped knees. Every playground becomes an irresistible physics lab when you understand the principles behind the fun!
