thingiverse

Human: Homemade Fly Trap for PET Bottles. To create a simple yet effective fly trap, start by putting something inside that smells terrible after fermenting in direct sunlight. Next, fill the bottle with approximately 0.5 liters of lukewarm water. The curious fly will undoubtedly be drawn to the container, following its nose to discover where the putrid smell is coming from. However, when it attempts to escape, the fly will try to force itself through the narrow opening until exhaustion sets in, ultimately leading to a tragic drowning.
