I found some awesome plans online for homemade fly traps. These come from a book published in 1915 back when people still did things for themselves. The book is Shop Projects based on community problems. What a concept! It does make sense though considering the time period. This was the age of American Functionalism, an early movement in psychology that said we should apply the ideas of psychology towards making a better society and teaching children to be good citizens. These ends were to be achieved through hands on, practical tasks.
So here’s the basic idea. I will update this as I build it or maybe we should have a class on it. Hmmmm.
