My 6th grade son's class is studying a geology unit in Science and I thought we could make something for him to take in to share with classmates. My 4th grader actually ended up making these. He masked up, used the dremel to rough up a spot on the back and super glued on a magnet. There ended up being plenty for each of them to take in for their science classes. They can take them home for the fridge, put them in their lockers for hanging notes or, more likely, chuck them at each other on the school bus. 
We'll end up making more of these to give to family, friends, whoever will take them. It's probably a better way to display tumbles than having them sit in a bowl. Not every stone will work, but I have plenty that are thin enough and flat enough on one side for it. My next saw session, I will be cutting more slices than usual.

Nice project. Who knows, it might inspire some young person to start hunting for rocks.

Might be something to sell at craft shows.

Might be something to sell at craft shows. I thought of bundling some to sell, but I don't think I'm up to having a booth at a show or anything. I may set up a table of tumbles, magnets and such in the driveway the next time we have a neighborhood yard sale. Not too much to lose giving that a try. |

Those look great! I've made a few of these myself, they make great Xmas stocking stuffers! They make self-adhesive magnetic "tape" that makes the task even easier, I think I may have gotten some from Walmart or the Dollar Store.

NICE idea! I am always looking for ways to showcase my tumbles and cabs to my extended family and friends. I like!!! Thank you! Glenn |

Great idea Randy Garage Rocker . I saw unclesoska 's suggestion, but I'm curious what type of magnets and glue you used. |

Dave, I used regular super glue and cheap craft magnets from either Wal-Mart or Michaels, can't remember. They weren't the rare earth kind or anything. The backs of the stones were scuffed with the Dremel, but I reckon sandpaper would work as well.  |

Your rocks are awesome. They deserve neodymium magnets. 1/2" diameter x 1/16" thick work great and will actually work to hold things on the Fridge. Craft magnets not so much. I have a display that I keep mixed rock tumbles on at rock shows and they barely sell at $2 each but I sold over 100 pudding stone tumbled magnets last year to a gift shop that sells them at $10 each. Go figure.   The pudding stone ones are usually not flat tumbles. I hold one side against a 100 grit flat lap disc for a couple seconds until I have a 1/2" flat spot to put the magnet.  These magnets are great and really cheap when you get 100 at a time on Ebay. Your glue is probably fine but anything I glue to a rock gets 5 minute 2-part epoxy. I have seen issues at shows out in the sun with lesser adhesives.  .17 cents a pieceChuck |

Been looking for a way to show and gift give my stones in a practical fashion.....everybody has a magnet on their fridge.......now they can have a polished stone too.....! Thanks so much for the idea. |

Those look great, Randy. That’s a nice way to give the rocks to kids. I like the idea of using them in their lockers.

Thanks, Chuck, I remember seeing your display in pictures of your booth. I'm not opposed to using better magnets, at all. If I had thought to make these ahead of time, I probably would have ordered some. As it was, the idea to do it and execution took about an hour, including the trip to Meijer to get super glue. The magnets were already here from a previous school project. These were strong enough for one to hold photos, a sheet of construction paper or a school menu. Not a calendar, I tried. Anyway, they went to school today and were a hit, from what I hear. BUT, now I have been requested to come in to school and teach my son's class. After corresponding with his teacher, she has asked me to take an hour and tell them about tumbling, the types of rock I tumble and how they are formed, and anything about what can be found nearby. Where's 1dave when you need him??? I just hate that I've given away all my KY agate, other than a few tumbled pieces. It's the most interesting thing to be found around here and I'd like to show them some. |

Glad your magnets were a hit and not surprised. I was not trying to critique the magnets you used just offering some lessons learned. Rocks break pretty easy when they fall off a fridge onto a tile floor. Chuck |

I'll be placing an order for the stronger magnets before I make more. Luckily, I have hardwood in the kitchen, because the kitten jumped up and knocked a couple off while I was trying to get a photo. It's more forgiving than tile! |

Between what you and Randy have done, I now have an option for off-loading some rocks. I'm not looking to do this as a business venture, but it affords me an opportunity to give rocks in a meaningful way. This will be fun to play with. |

It's the most interesting thing to be found around here and I'd like to show them some. How fortunate for you, the teachers, and the children! My input: KISS - Keep it short and simple. 1. About agate: Openings occur in rocks. 1aa. gas bubbles in lava 1ab. spaces between rocks in slides. 1ac. openings left by dissolved minerals 1ba. pH (potential of hydrogen) is a scale of acidity from 0 to 14. It tells how acidic or alkaline a substance is. More acidic solutions have lower pH. More alkaline solutions have higher pH. Substances that aren't acidic or alkaline (that is, neutral solutions) usually have a pH of 7. 1bb. Low ph solutions dissolve calcium, High ph cause calcium to precipitate. 1bc. Silica is just the opposite. High ph dissolves silica, low ph causes it to precipitate. 1bd. as ph of solutions change, some substances are removed, others left to fill the openings with interesting colors and shapes. 2. The power of water. 2a. water seeps into tiny cracks high in the mountains and expands when it freezes, breaking the rocks apart. Broken rocks tumble down the mountain. 2b. Water keeps the rocks tumbling, breaking off the irregular parts, making them round. When big boulders are washed downstream you can feel the ground shaking as they pass by. 2c. softer parts are worn away, leaving the harder rocks like agates and gemstones intact. 3. We just continue that process of tumbling them with ever finer grit to remove smaller parts - BUT we prefer slurry to just plain water to cushion the rocks so they don't hurt each-other. Of course YOUR presentation will be much better than mine. |
