How can you make paper airplanes turn?

The same way an aeroplane does, so add some flaps (tear/cut the wings in two places on the rear edge) then fold one up and one down.

Hold a cat or your your younger sibling by a limb. Swing them around and hurl them at the plane. When they make contact with the plane, it should turn. It works for me every time with my 6 month old sister. Sometimes she cries after I throw her, but then I just shake her until she's quiet again. Babies love to be shaken, that's why they like rattles so much.

Try Foldin Up the wings a lil bit it could help or make the end pointer hope this helps (: x

if you fold the wings up. it can make it go up or down usually. but then again airplanes pretty much just go where they want.

hhh

get one of the wings wet a little bit. that will weigh it down and make it turn in that direction
