Recycled Bottle Helicopter

Prepare all tools and supplies like stated above and shown on the picture

Use scissors or any tool with small, sharp end to make a hole in the plastic cap. Try to do it in the middle and be very careful as you'll need all your fingers later.

Cut the bottle into two parts and also one stripe which will make the joint for skids (I know this is a special shape of a bottle but I am sure you'll find it somewhere). It should have that ball-shaped part to put the ping pong ball inside.

Now you need to cut three straws in a way shown (three parts with bent heads should be a bit shorter than the rest of the straw)

Use a pin to put two longer parts together making a propeller. Pin previously cut stripe to shorter straws with a stapler to prepare skids, afterwards stick the last bent straw, into the hole in a cap. Now you've got the three most important parts to build your mini helicopter with

The part with a cap should be now attached to the body with a stapler (as you can see on the picture).

The final action in your crafting experience is to put the ping pong ball into the body, forming a cockpit.

P.S. It is as easy as it looks like so DO try this at home and have fun!
