Density Lab: Liquid Sort

Density Lab is a calm liquid sorting puzzle with a twist from real science: heavy liquids sink and light liquids float. Pour colorful layers from flask to flask until every flask holds a single color.

HOW IT WORKS
• Tap a flask to lift it, then tap another flask to pour
• Heavy liquids, marked with down arrows, sink beneath anything lighter
• Light liquids, marked with up arrows, always float on top
• Ghost layers preview exactly where a pour will settle
• Solve each experiment in the fewest moves to earn three stars

200 LEVELS IN 8 LABS
• The Apprentice Bench teaches the density rule one step at a time
• Bottom-tap flasks drain their heaviest layer first
• Hidden layers reveal their color once nothing covers them
• Frozen flasks thaw after a few pours
• Bigger flasks hold five and then six layers
• Every level is checked by a solver, so every puzzle can be solved
