Talking about getting really eco-friendly! An interesting electric powered toy gun gets tested by Hyperdouraku. Called the Zhi Lun M4 Storm, this gun fires 10mm "Water Bullets" that weigh 5grams. The ammo is fed from the top in the shape of a "scope" which will remind you of the Paintball Hopper. It is powered by 6 AA Batteries that are installed in the magazine area. If you watch the video, it fires sluggishly and according to Yas, it barely reaches a distance of 10 metres.
