"Hey there! I'm trying to shoo the birds away from these power lines. Each time I clap my hands, half of them fly away, but one comes back! This pattern never fails. Even if I stand here clapping my hands all day, the number of birds always ends up right back where it started!"
So, how many birds were there on the power lines to start with?
- UK Version
"Coo-ee! I'm trying to shoo the birds away from these wires. Every time I clap my hands, half of them fly away, but then one comes back! The pattern keeps repeating itself. Even if I stood here clapping my hands all day, the number of birds would always end up right back where it started!"
How many birds were there on the wires originally?
Don't let the birds win!
Two birds is correct!
Half of two is one, so one bird flies away and then comes right back. So the number of birds always ends up being two.
In this puzzle, using "half" to refer to one bird is potentially quite misleading. Be sure to choose your words carefully, even if you're explaining something simple.
