Race Around the Black Hole

In this game, learners cutout a model black hole "cone" and attempt to roll around a marble or other small spherical object without touching the event horizon. Black holes are gravity to the extreme; if an object goes past a black hole's event horizon, it can never get away. Includes the black hole cutout with craft and game instructions, a note about friction in the model compared with real space, and additional information on the first image taken of a black hole.
