I believe other essential features of bagels in the lab are that they remain fresh without refrigeration, they don't leave grease stains or get your fingers sticky, and partially eaten portions keep until you return (if science interrupts you in the middle of a snack).
Uh, I'd be more worried about the drinks getting into the equipment if spilled. And the ESD generating properties of the plastic containers. We got rid of styrofoam cups a few years ago in favor of paper - help the environment and cut ESD at the same time, but I make a point of not bringing drinks into the lab ever and encourage others to do the same.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
