Using 2D and 3D shapes to make air rockets

We wanted to make rocket tops that we can launch with teacher's rocket launcher.

We discovered that a 2D circle can change into a cone just by cutting the middle half way and squeezing with our fingers.

We discovered that a rectangular card can be rolled to make a cylinder.

We know that triangles will make great fins.

Now we are ready to assemble our own rockets.

Our rockets are ready for launching now!
