Answer 2

Using the ruler, mark with a pencil the outline of a 4cm x 15cm rectangle.

Cut out the outlined rectangle and discard remaining paper.

Crease the rectangle down the center of the paper on the 15cm length side (see photo). Unfold to flatten paper, you should be able to see the crease that you made.

Fold the rectangle down the center of the paper on the 4cm side (see photo). Then unfold the paper, you should be able to see the crease.

Cutting on one side of the 15cm crease, make an incision almost the center crease. (stop cutting at 1cm before the crease that was made on the 4cm side)

Make a 1cm incision on each side along the 4cm crease.

Using the incisions made in step 6, fold flaps so that they meet in the middle

Using the pieces you just folded, fold the two flaps together so the faces are touching

Making a T, fold the cuts you made in step 5 in opposite directions. This will be the top of the T.

Place a paper clip on the bottom of the T.

Drop helicopter from any height and watch fly!
