I invented a leaf blower that is 100% silent and is shaped like a rake.
Interesting, my rake makes some sounds when I use it. It’s pretty loud on hard surfaces.
Let me just rake up all this sand and grass clippings.
Too bad there isn’t one shaped like a broom.
I think we're on to something here. Like, different rakes for different things to rake up. Brilliant!
That's way too expensive. I just use my fingers.
Can I borrow them to clean my yard? I promise I'll get them right back to you.
