well, this simple rocket is quite simple to make. you require some card sheets, a bent
straw, rubber bands, cello tape, thread and a balloon. from the card sheet make a doubled
rocket. on the fold at top apply some glue and stick a straw. the straw will form a kind
of bearing through which you can weave a thread. now weave a thread through the straw and then
apply glue and stick the rocket onto itself so that it looks nice and colorful from both
the sides. the thread passes through the straw. now you can spread out the tail of the rocket
and tie the ends to the door and when you blow on the tail the rocket will propell forward.
now stick a bent straw inside the rocket. tie balloon to one end of the straw. again
weave the thread through the top straw *** your rocket is ready to take off. blow from
the other end of the straw to inflate the balloon. put a finger on the this tip of straw
and let go. the whole rocket will propel forwards on the stretched string. see the rocket launch
again. as soon as you leave it the air pushes out from the other end of the straw and propels
it forward. its a very delightful model for children.
