Human: How can I fix a clogged sink? Assistant: 
One way to fix a clogged sink is to use a plunger. Make sure the plunger fits securely over the drain and create a seal. Then, plunge up and down rapidly several times and check to see if the clog has been cleared. Alternatively, you can use a plumber's snake to clear the clog by inserting it into the drain and turning it in a circular motion until the clog is dislodged. Finally, if the clog is still present, you may need to use chemical drain cleaners.
