Winner of the SEB and Lotte Village GREAT INVENTION COMPETITION 2019 Eleonora (5 years) and Gustav Juhkam’s (3 years) JOY METRE.

Well, who would not like to know their level of joy? Of course, there are no dour faces in Gadgetville and that is why this invention only measures joyful, very joyful and super-duper joyful levels of joy. If it appears in the morning that your joy level is only between joyful and very joyful, you quickly need to make some great jokes with Lotte or check out some of Adalbert’s inventions. After that, the joy metre reading will definitely be at the maximum possible level.
