To solve this puzzle, the bird will have to learn how to pull up a piece of thread at the end of which is a peanut.
You will need:
A plastic tube (the sort that bath flakes come in), a matchbox tray, a mini peg from a toy shop, thread, a drawing pin and a peanut.
|
|
|
Take a length of thread and push one end through the hinge of the peg and tie the thread in place.
|
|
|
 |
 |
 |
|
|
|
|
Now tie the other end of the thread onto the tube, make sure you tie the thread under the lip of the tube so it doesn't slide off.
|
|
|
 |
 |
 |
|
|
|
|
Open the peg and clip it onto a peanut and then drop the peg into the tube.
|
|
|
 |
 |
 |
|
|
|
|
Now snip out a circle in the bottom of your matchbox tray. The circle needs to be big enough to hold the tube in place but not so big that the tube slips through.
Keep checking the size as you go, because if the hole is too big you can't make it smaller again!

|
Stick a drawing pin through the back of the tray so you can pin your brainteaser to a tree when you have finished.
|
|
|
 |
 |
 |
|
|
|
|
Now place the tube in the hole in the matchbox tray and pin it to a tree.
Sit back and wait for the birds to figure it out!
