The floor caught it. See another.

A strange thing

• You are standing still. Gravity is pulling you down. Why don’t you fall through the floor?

• The sun is shining. A dark shape sits on the floor. What is making it?

• A car is heavy. Why doesn’t it sink into the road?

• They are not touching. So what is pushing?

• A nail sinks. A ship made of the same kind of stuff floats. What changed?

• The flash arrives. Then the bang. Why the wait?

• If Earth pulls the Moon, why doesn’t the Moon hit us?

• The paper did not get stronger. So why can it hold the coins now?

• You used it. Now it is warm. Where did the warmth come from?

• You throw a stone. It leaves your hand and falls. Something that keeps pushing can leave. What changed?
