Week 8 Update: Chameleon's Tongue, first Test

Over the course of this week, the tongue section of the design was built and tested. Rectangular pieces of polyethylene material were rolled and sealed using a hot glue gun. The tongue body was then sealed on one end and attached to the air blow gun using a pipe clamp on the other end. A 1 foot 3 inch tongue was first tested to see if the tongue design was feasible:

The tongue was then extended to 3 feet but failed because the air tore through the sealed bag:

The tongue was then shortened to 2.5 feet, rubber bands were also added to retract the mechanism. The rubber bands were clamped down by the pipe clamp and attached to the tip of the tongue. The design was not operational as the rubber retracted the tongue before the compressed air managed to fully extend the tongue:

It was then concluded that the tongue needed to be shortened considerably for the design to be functional.
