Zero Plank

Only sharp minds hit 0.0°. Zero Plank is a quick, cute physics puzzle: drop animals onto a seesaw and leave it perfectly level. Every animal has a weight, every spot has a distance – and the plank tips by weight × distance. Land it dead level and the zoo cheers. Tip past 30° and everyone tumbles off.
