deoderant stick and continuous servo

The bubble solution will be placed inside the cup and will be raised to the wand.  In order for this to work I cut a deodorant stick as shown

 and screwed a servo arm to the bottom.

Although it is not shown in this picture I ended up using duct tape because the arm was still able to move.  After that was completed I hooked up the continuous servo motor to the bottom and taped the servo to the stick at the bottom.

Here is a video of the motor moving the cup up and down.

Now that I have this part functioning I can begin messing around with the code so that when the cart is directly under the bubble solution the cup will rise.
