A few days ago I read a very fun book. It is about lots of funny and useful inventions. I am going to tell you three cool inventions. The first one is called a Testing Spoon. It’s easy to do, you just have to stick a thermometer on a spoon. The way to use it is that.when you’re drinking soup, you pour the soup onto the Testing Spoon. The thermometer’s mercury can tell you what’s the temperature? So now you will never burn your tongue again.

The second invention is called the Dog Cleaner. This invention is easy to build too. Tie a brush on a dogs body. Tying on the dog’s belly is the best. The way to use it actually it’s the dog using it. The dog will walk around and the brush will clean the dirty floor, for example. The dog can walk around and can clean things in your house. So if you have a dog in your house, then you can make one.

The last invention is called the Exercising Shovel. This invention is easy to make too. Just make a hole in a shovel. The way to use it is simple. When you are digging, most of the dirt can’t be lifted. So you have to dig more times. That’s how it helps you to exercise. All these inventions are ridiculous, but they are all useful things. I think you should buy the book.
