Traffic lights shake

Another of the greatest human inventions has been the traffic light, so on the occasion of the International Inventors' Day, we recommend you to make a traffic light-shake in  honour of two inventors: John Peake Knight, who invented the first manual traffic light in the middle of the nineteenth century, and Ernest Sirrine who improved it by making it automatic.

For this smoothie, full of vitamins, we used fresh strawberries, banana and kiwi: first crushed the strawberries and serve in a glass, let it a few minutes in the fridge in order to increase the consistency. Then add mashed banana, and again let stand a few minutes in the fridge. Finally add the kiwi.
If you prefer a more intense yellow colour, replace the bananas with peaches.
