Scientists have discovered the best way to swat a fly. Apparently flies are so hard to swat because they have the ability to plan and carry out an emergency take off in under 200 milliseconds. The trick then is to creep up on the fly and then try to anticipate which direction they are likely to fly to. It works because flies are unable to register slow movement but it still relies on guessing which direction the fly will go so doesn’t seem entirely fail safe. We have a device in our house for catching flies, his name is Oliver and he rarely misses, catching them in mid air. Every house should have one.
