Great job! We have learned enough about flying! Now let's experiment with flying!

Here's what you need.

STEP 1: Take a tissue roll and cut it into half.

STEP 2: On the cardboard, sheet draws two circles of the size of the tissue roll.

STEP 3: Let's cut the two circles out!

STEP 4: Next, cut the top part of the bottle using a paper cutter.

NOTE:

This step has to be done with the help and guidance of an adult. 

STEP 5: Poke a hole in the cap and pass a pencil through it. 

(Use the scissor to make the hole).

STEP 6: Next, let's take one of the circular cardboard cutouts and cut a hole through the centre to fix the top part of the bottle like this.

STEP 7: Seal the top and bottom part of tissue roll with the two cardboard cutouts

STEP 8: Check if it is sealed properly, apply glue where necessary.

STEP 9: Mark three points using a pencil on the tissue roll. All these points have equal distance between them.
Skip to STEP 12 for better understanding.

STEP 10: Make a hole, big enough to fit a straw inside. Do this for all three points.

STEP 11: Take a straw and cut a 7cm part of it. Chop the neck, as shown in the image below.

Do this for the other two straws as well.

STEP 12: Fit the straws inside the 3 holes we made in STEP 10.
The air will come out from the straw openings causing it to spin. 

STEP 13: On a piece of paper, draw three equal rectangles of the size given below.

STEP 14: Cut them out and stick them on the top of the straw.
*These are the wings of our Ballooncopter.

STEP 15: Finally, inflate a balloon and attach it to the top like this.

See your Ballooncopter flying!
