Cow Filter 5000

Johnny

Age 12Markham/Ontario, CanadaApr 2024

Back to all ideas

This is called the cow filter 5000. It is for the farmers who have cows and maybe other animals. It filters out methane when the cow farts. It works when you stick the cow's bottom to the pipe and next you tie the two strings on to the cow's back.

Little Inventors team says

Dealing with cow farts isn't for everyone Johnny, so it's good that you invented a filter to do it for us! Hopefully the seal is strong enough so no smells escape the pipe. Methane is a harmful greenhouse gas, so taking steps to control it is great for our planet. Keep inventing!
