1 KG spoon,knife,fork
Here you can see a picture of a fork,knife and a spoon that has a very interesting features. All of these eating instruments has a 1 kg weight at the point where the handle should be. When you are eating with these table tools you are lifting weights and with every bite your biceps are getting stronger. Of course this is just a commercial or a funny art project because those things are not very comfortable in your hand and i am not even talking about how could it feel when you need to eat with them.
