Kids are taught to never play with fireworks, but the Sega Indoor Fireworks Projector makes fireworks safe enough to be used indoors. This device is able to beam realistic virtual firework displays across walls and ceilings, and it even plays accompanying explosive sound effects. The system utilizes 6 lenses, nine interchangeable image discs, and internal speakers. But you can also hook up external speakers to it for an even more powerful effect. And the system comes with 9 discs with 5 designs on each  so you’ll be able to pull off a very artistic show! The Sega Indoor Fireworks Projector retails for £129.95 (about $214).
