Australian Open: Edouard Roger-Vasselin's Covid quarantine chain reaction machine

Tennis star Edouard Roger-Vasselin has been getting creative during his quarantine time ahead of the Australian Open.

The Frenchman has made and filmed two Rube Goldberg machines in his hotel room over the past week.

Players are required to stay in their rooms for 14 days, a small number testing positive for Covid after arriving in the country.
