Which is heavier?

About Which is heavier?

The fastest way to test your weight intuition: two real objects appear, you tap the one you think is heavier, and the weights are revealed instantly. Every correct pick extends your streak — one mistake ends the run. The pairs always differ by at least 30%, so there's always a right answer, but your gut will still betray you more often than you think.
