Pneumatic Candy Canon Delivers COVID-Safe Halloween
Halloween is big deal in our household. Now is the time when I start thinking about how we might revise or update the presentation. With the onset of COVID, in 2020, we decided to skip the year. Prior to the availability of vaccines there was no way to ensure a safe experience with what has historically been a large crowd.
In 2021, given the availability of vaccines, we opted to resume engagement with trick-or-treaters. However, we did so taking precautions to keep our boo-crew at a safe distance from the kiddos. The core of this strategy was not allowing trick-or-treaters into the yard.
Instead, we enhanced the decor along our fence line, and delivered candy to the front gate using a pneumatic candy canon. While not yet perfect, this worked quite well. This post details some of the design considerations, experiments, and lessons learned in creating the candy canon.
Others in the neighborhood were experimenting with using PVC pipe to create a candy chute from a second story window to their fence line. This was nice and simple, since gravity did all the work for you. However, ours is a single story home. Further, we didn’t relish the idea of Boo Crew on the sloped roof.
I thought it possible to use air pressure to push the candy along the tube, not unlike the system we find at drive-up banks or pharmacies. I could use our existing Shop-Vac in reverse to generate the air flow, connecting it to a length of PVC pipe.
