Quiz | Easy like Sunday morning: The many records set on August 27
1 / 10 | On August 27, 1783, French scientist Jacques Charles and his team launched a balloon that eventually reached a record altitude of 900m. Earlier, all attempts had used hot air, but Charles studied the behaviour of gases, so chose a different path. They engineered the balloon with silk sheets, rubber and turpentine, making it possible to hold a very light gas. What gas did Charles use, which till an unfortunate incident, powered balloons for years?
