Another lovely night playing "conservation of energy" with my daughter. The box says 8+ but I would easily give it a 10/10.

She-Hulk plays ball in Avengers #31 (2000) #SheHulkSunday #classicalmechanics #marvelcomics
A full page from Avengers #31 (2000) showing She-Hulk playing ball with Triathlon in the combat arena. She-Hulk launches the ball as hard as she can, declaring that Triathlon won’t be able to stop it. He responds that he doesn’t need to stop it, only deflect it at the right angle. After a final bounce from She-Hulk’s head, it hits the goal and Triathlon wins.
