I want to start selling "magic bricks", like they used to sell, about 25 years or so ago, again. What's a brick cost? Like 50 cents? I think the local place that had them sold them for either 39.95 or 49.95. Figure 100% markup, it's still not bad.
Anyone got one? I saw one at a ham radio show a few years ago, and haven't seen one since.
