The children seemed to enjoy playing with the toy and were usually able to find the best combination of parts after trial and error. It was more difficult to get consistent results than expected due to some issues that were unaccounted for. The trigger mechanism didn’t work at this point, so each launch varied depending on the child's ability to pull the handle back fully and release it in a fluid motion. Also, the marshmallows had inconsistent diameters, which caused the results to vary. The children were occasionally confused as to why the same configuration of the launcher would sometimes launch the marshmallow across the room and other times not launch the marshmallow at all. With the trigger mechanism now functional, the force produced should be more consistent for each combination, but the inconsistencies of the marshmallows will still result in varying results. Overall it was a successful project, and many of the children were able to have fun launching marshmallows across the room, under chairs and tables, and occasionally into the hair of a bystander. It would have been nice to have multiple marshmallow launchers so multiple children could participate simultaneously, but unfortunately production time was too long to make more than one. From this project we learned that even for toys that seem simple, the production can be difficult and time consuming, and that there is little room for error. Additionally, ideas that work conceptually don't always work the same way in practice, so it is important to test a simple form of the design before spending huge amounts of time on something that may not work. Our trigger mechanism was much more difficult to construct than we originally planned, and it would have helpful to test various options before attaching one to our project. In the end it worked with some modifications, but required more work than we expected.
