This “fire ball” lets you extinguish small fires from up to 6 feet away. After a devastating hotel fire, Thai inventor Phanawatnan Kaimart wanted to create a fire extinguisher anyone could use safely. The Elide Fire Ball only weighs 3.5 pounds. When activated, the ball emits a warning noise and releases fireextinguishing chemicals. The chemicals are not harmful to humans or the environment. The invention holds a patent in 98 countries.
