Your turn
BE THE ROCKET ENGINEER
Can you design a rocket that stays in the air longer than your friend's?
YOU GET: 1 sheet of paper · 1 straw · tape · scissors
THE EXPERIMENT — change ONE thing at a time
Keep the same (controls)
- Same straw
- Same launch (one big breath)
- Same way of measuring
Change ONE (variables)
- 01 Nose shape
- 02 Fin shape
- 03 Mass (add a paperclip)
Change two things at once and you won't know which one worked — that's the secret of every science experiment.

Send a photo, your best time, and what you changed. Tag @buildbirds.in on

(Three flights, same launch, one change at a time — that's a result worth sending.)

Real rockets — from day one
You don't need a launch pad. Just a straw and a Saturday.
Every step is real flight with real data: build, measure, change ONE thing, measure again.
That loop is the job. (Engine motors need a licence in India — clubs and school comps fly those.)

Mission 002 + the 3D-printing teardown drop here
It flew badly? Good — that's data. Read it:
IT WOBBLES & TUMBLES
Unstable. Fins too small, or too far forward. Bigger fins, right at the tail.
IT DROPS LIKE A STONE
Too heavy up front. Take the paperclip off and fly it again.
IT GOES FAR, NOT LONG
Launch angle too flat. You want hang time — aim steeper.
