This is a funny book about many kind of inventions.In this book, Adam Kay wrote many incorrect facts on purpose, but his robot butler used “?fact check?” to correct all of them.
I know what is blue tooth,I want to know why is it called “blue tooth”,I learned that it’s named after a Viking king from a thousand years ago who was known as Harald Bluetooth. It’s named after him is because he want different tribes talk to each other, it is a bit like how Bluetooth brings together our phone,our wireless printer and our fridge.(I think it is just the best fact to do the KWL, there’s many more.)Bye!
