¿ªÔÆÌåÓýAs a teenager I bought pure lithium metal.? It was supplied in a jar covered by oil. I cut off pieces and threw them into snow or ice for instant fireworks. Bertho ? ? From: [email protected] <[email protected]> On Behalf Of wn4isx via groups.io

But no one was listening to me when the phone went up in flames and someone grabbed a child's squirt gun and 'zapped' the phone, instant flare up and another person used a paper plate to push the phone in a cooler filled with ice and water. The ice might have slowed the reaction a bit...then again not enough to matter. ? Instant cloud of steam and flaming bits of plastic. ? By cloud of steam, I've played with smoke grenades, legally in college, and the wall of steam was at least as large as a typical military smoke grenade cloud. ? But all fires end when the fuel is gone. ? One good thing was the phone melted the bottom of the cooler, which let the water out, which put out the small grass fire the flying flaming bits of whatever started. ? The best part was the fire department....I simply sat there, kept my mouth shut and let others explain what they'd done and why as they "grilled" us.? ? At least the food wasn't harmed.? ? The city was very unhappy because the phone left a deep burn scar on the picnic table...I guess they complained to Samsung. ? If it had been up to me, I'd have knocked the phone to the ground, called 911 and then used water in the cooler to put out the inevitable grass fire and let the phone burn itself out. ? I view our lithium battery powered equipment as "incendiary devices in waiting." ? ? |
