Ivan Fletcher loves crazy invention. He writes a Weekly magazine column called "Unbelievable Inventions"

   "One of my favorite inventions is the Butter Stick. It looks like a Stick of glue ( 膠 ), but it's butter. You rub it on the bread instead of using a knife," he says. Another cool invention is Duster Slippers for pets. You put these special shoes on your dog or cat. As the animal runs around your house, it collects dust from the floor. Very useful!" A lot of these inventions come from Japan m the home of the crazy invention.

   Ivan says that the British also invent a lot of crazy things. "The other day I found an invention called a Cat Seat Saver," he says. "The Cat Seat Saver looks exactly like a sleeping cat but it isn't real. You put it on your scat if you have to go to the restroom. No one will sit on your seat because they think there's a sleeping cat on it. Pretty cool!"

  However, does anyone buy these things? Yes. Lucy Wade from the shopping website crazygadgcts.com says that their customers are young, professional people.

  "They buy these small things mostly for fun," she says. "They arc usually looking for a present for a friend's birthday or a silly gift for a colleague."

   If you have an idea for an amazing invention, send it to Lucy at lucyw@crazygadgets.
