Train Wreck

Organized train crashes used to be a thing
back in the day, believe it or not

Speaking of things crashing, try Train Wreck to spice up your Alley Rally. In Alley Rally, young beginners stand on either side of the alley and pass a ball back and forth to each other. Train Wreck ups the ante by having them pass and receive TWO balls simultaneously. As with actual trains, you do NOT want the balls to hit each other, so a modicum of control is required. Challenge your players to see how many passes they can do without a 'wreck'.

Progression
Still too easy? Increase either the number of passes required or the distance apart.
