Visitor in Blackwood Grove

A mysterious Visitor has crashed in Blackwood Grove. Race to figure out the secret rule as the Agent or the Kid in this induction game! A spacecraft crashes in Blackwood Grove, and the kid is the only one watching. Federal agents hunt down the signal, but no one can get near the craft due to its crushing forcefield. Why can some objects pass through it, but others are repelled? Experiment with what can pass through the forcefield, figure out the rule, and reach your goal.
