During the workshop, we had an opportunity to assemble and play with a scale model of the Earth-Moon system to help us better understand the origin of the lunar phases as well as lunar and solar eclipses. With the proper amount of caution, you should never be injured.
Injuries result from improper tool use, carelessness, and fatigue.
Again, please exercise appropriate caution when using tools. Then, using the drill, carefully drill a hole that allows a snug fit of the coffee stirrer into the hole. If you are unsure about what size drill to use, start with one that is visibly smaller than the coffee stirrer. Check if the stirrer will fit into the hole. If not, then use the next size larger drill and repeat until the coffee stirrer snugly fits into the hole.
