Brainsnag Level 10 answer: Stop the Leaks
The level says: “Stop all the leaks”
Hints first (no spoilers)
Hint 1One finger stops one leak. For a moment.
Hint 2All three must be stopped at the same time.
Hint 3Press all three holes at once with three fingers, or drag the tape across all three holes in one go.
Show the full solution
Covering one hole does nothing while the others spray. Press all three holes at the same time with three fingers. On a computer, drag the roll of tape across all three holes in one continuous motion.
