SPRING

We bought a toy for use the spring that this had, for we could do prototypes, at the time of testing the toy, we realized that this provided a new idea which we had not worked, that was the convination of the spring and the tube sucking the air, an interesting idea.

CONCLUSION:

Expected positive feedback: Fly about 15 meters.

Unexpected positive feedback: It's a good combination. 

Expected negative feedback: It's needed much force for Jana this mechanism is not good

Unexpected negative feedback: /

We perform different ideas for a prototype, we want to use elastic spring like mechanism principal, these are some of the ideas realized.
