Tube

How it works

• Small round balls and water roll through it, following its ups and downs under gravity.
• A round thing goes in only if it fits the mouth and is moving in. Larger balls and crates bounce off.
• It passes over and through other parts without touching them, and laser beams pass through it.
• A ball comes out of whichever mouth it reaches.

Tips

• Face a mouth towards where the ball will arrive.
• Drag the middle knob to bend the tube.
