    I didn’t think a rock would bounce that high.

    The coefficient of restitution of the rock seems to be greater than 1.0, which means each bounce will be higher than the last until the rock reaches escape velocity. Since energy must be conserved, the rock will absorb heat from the environment, setting off a new ice age.

    I remember the lazy summer day my siblings and I discovered golf balls bounce. That was fun.
