This little rocket costs next to nothing and can achieve amazing altititudes.
All credit for this rocket should go to pudi.dk as his "ultimate straw rocket" gave me the idea for this one.
This is my first instructable, be as harsh as you see fit, all criticism is welcome but do be fair.
Step 1: Materials and tools
skinny straws(not flexy straws).
larger straws(still not flexy).
hot glue gun sticks.
a BIC pen.
A foot pump.
A pair of scissors.
a skewer (for dismantling the pen).
