Regular flares, while fun to place in sleeping friends’ beds, are smoky, poisonous, and dangerous. These flares, on the other hand, are small, rechargeable, and are strong enough to be run over by a truck. But what about flare wars where you and your drunk father throw flares at each other, you ask? Well, don’t think these things will replace those wonderful evenings spent in the company of your angry Old Man. Instead, consider them a high-tech, eco-friendly alternative. And they still hurt if you throw them at someone.
