ding dong by raphael rohart from france

As a bell, the functioning of Ding Dong is based on its balance. The difference is that Ding Dong doesn't solicit hearing but touch and sight.
Find its balance and make it stand up (touch sense) to switch it on (sight sense). Just make it fall to switch it off.
How it works: A metal ball connects the 2 metal pins in the globe when Ding Dong stands up. The contact naturally disapears when you make Ding Dong fall.
The grip top part is made of silicone and cushions shocks.
