Helicopter From Straw

I made this helicopter from basic items in our life. Hope you like it.

We use two straws which have equal length.

Place them perpendicular to each other at the midpoint.

Use a pushpin to attach them to the body.

Use a piece of ball which has been drilled.
Pass a straw through the hole of this piece.

Join all of these parts together.

You can see it clearly in the video attached here.
