Brain Out 2 Level 170
📝 Walkthrough
Overview
Level 170 says "All I want is egg yolk!". An apron-clad woman stands in the kitchen holding an empty plate. On the counter there is an egg carton with three whole eggs and, on a plate, a single raw egg yolk. The clever part is a plastic bottle lying on the shelf to the left, which is the tool the hint refers to. You use the squeezed bottle as a suction cup to lift the yolk from its plate and transfer it onto the plate the woman is holding. The solved state shows the woman holding a plate with just the yolk, smiling.

- Estimated moves: 3
Step-by-Step Solution
- Understand the goal. The woman wants only the egg yolk, not the whole egg. A raw yolk is already sitting on the plate on the counter.
- Do not crack another egg. The three whole eggs in the carton are not needed; the yolk she wants is already separated on the plate.
- Take the plastic bottle from the shelf. On the upper-left shelf there is an empty plastic bottle. This is the "tool".
- Squeeze the bottle and suction the yolk. Press the bottle to squeeze the air out, place its opening over the egg yolk, then release so the yolk is sucked up into the bottle.
- Transfer the yolk to her plate. Move the bottle over the plate the woman is holding and squeeze again to release the yolk onto her plate.
- Confirm. The woman now holds a plate with just the yolk on it, smiling with sparkles, and the text reads "Clever use of tools!".
Strategy & Reasoning
The level is a play on a real kitchen trick: an empty plastic bottle can be used as a suction tool to suck up an egg yolk without touching it. The hint "Clever use of tools!" points you toward the bottle on the shelf rather than toward cooking.
The naive approach is to crack one of the whole eggs or to pour the existing yolk by tipping the plate, but neither uses a tool. The bottle is the deliberate object: squeeze it to create suction, lift the yolk, then deposit it on the woman's plate. The empty plate she holds is the destination, and the carton of eggs is a distraction. The physics is simple — compressing the bottle pushes air out, releasing it over the yolk creates a vacuum that draws the yolk up, and squeezing again pushes it out onto her plate.
Tips & Common Mistakes
- Mistake: cracking a whole egg. The yolk is already on the plate; you do not need another egg.
- Mistake: ignoring the plastic bottle. The empty bottle on the shelf is the tool. Squeeze it to suction the yolk.
- Mistake: trying to pick up the yolk by hand. A raw yolk breaks easily. Use the bottle's suction to move it cleanly from the counter plate onto her plate.
- Hint: If the yolk does not lift, make sure you squeezed the bottle before placing its opening over it.
