The Iridium satellite system is good for a magic trick. The satellites have two big shiny antennas, like wings, that reflect a bright beam from the sun. Think of holding a mirror in the sun. The direction of those reflected beams depends on the position of the satellite and the angle of the antennas to the sun. Those beams occasionally sweep across the earth and some are easily visible. It looks like a star suddenly appearing, getting brighter for a few seconds, then fading away and disappearing. Sometimes they’re bright enough to see in daylight.
So the trick is to tell someone that you’ve been practicing making stars, and you’ll show them one. A bit of grimacing and grunting, the star appears, you relax and it fades away, and you explain that you’re still working on it. Wow! Of course, you have to know when and where to point.
Turns out there’s a website
http://www.heavens-above.com You register your location and click on Iridium flares for the “next 24 hours” or the “next seven days.” You’ll get a list of a couple or several flares with the exact time, azimuth (angle from north), and altitude (angle above the horizon), along with the magnitude or brightness. You want the larger negative numbers for the brightest light. For example, I think Venus is around -3 magnitude and the moon is around -12. The brightest Iridium flares are -7 or -8.
So get a list, practice once or twice to get a feel for them, pick someone gullible, and give it try. Have a ready excuse for when they ask “Do it again!”
The International Space Station (ISS) is also frequently visible, and you can get info from that same website. You can try to pass off the ISS as your attempt to make a comet or really slow shooting star.
Around August 12 you get the real shooting stars, and lying on the beach at Lake McD or out on the boardwalk at the Pass are great places to see them.
