BB, the BuildBirds mascot, flying a rocket
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 your build
Send a photo, your best time, and what you changed. Tag @buildbirds.in on Instagram — or scan 04 below; the submission link goes out on the channel.
(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.)
Today
Straw rocket
Paper, tape, one breath. Indoors.
This weekend
Water / stomp rocket
A bottle and a pump — or one stomp. 50 m+, outdoors.
Tonight, free
OpenRocket
Any rocket, any motor. Crash it for free.
This year
Club launch
Real motors, licensed club. You bring the design.

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.
