A lot of people take selfies. A selfie is a picture of you. Some people use a selfie stick. You put your phone on the stick. Then the phone can take a better picture of you

The stick and the phone work together. No wire connects the stick or the phone. The two things communicate wirelessly. South Korea says that this is a problem. The country says that this makes problems with radio signals.

South Korea controls selfie sticks. Over there, you must not use some selfie sticks.

Difficult words: stick (a long thin piece of something), wire (a metal line), wireless (without a wire).
