I got this for my 7 year old grandson, along with the rock science kit. It was overheard him telling his sister, these are very special, I will keep them forever! Great value, a lot of bang for my buck!
This works great and isn't all that loud (I keep it in the garage). The instructions are very vague, so here are some tips.
The water...put enough water in the tumbler to cover the rocks, etc., along with the grit. After a week of running for 24 hours, check your rocks for desired smoothness.
When ready, clean the rocks (water) and clean the tumbler thoroughly. DO NOT do this in sinks, the grit will clog your drains, like cement was poured into them.
Always put a slight amount of cooking oil around the inner cap and around the lip of the tumbler (the instructions for this come with your purchase).
Repeat the water process with the rocks 2nd stage of grit. Wait a week, but tumble these 24 hours a day. Check the rocks for desired smoothness and repeat cleaning process, start all over with the next grit.
The 4th step, the polish. Run for a week @ 24 hours. If you would like the rocks, etc., to be even shinier and better polished, clean out the tumbler and add about 1/4 cup of Ivory Bar Soap. You need to make the pieces shredded, like shredded cheese. Run until desired shine is achieved.
Be patient, this process from start to finish, takes at least a month.
Have fun and enjoy!
After using this kit my daughter and I were discussing different ways science is used in everyday life and she looked at me and said, "Mommy, sciences awesome!". I felt as a teacher , as a mother, and as environmental biologist both excited and hopeful for the future! Every child, every person on this planet should be involved with science and how it impacts our lives! This kit is an introduction for young minds to become involved in science, to start a conversation, and it was truly an awesome experience to watch the moment of discovery on my child's face.
We had a really great time making this on Christmas Day. It was like an art and science project in one, the whole took us several hours, first building the frame for the volcano, then plaster strips and dry time, followed by painting, more drying and then blast off. We recommend you use food coloring in the baking powder and vinegar for the full effect, Awesome! great memory made with this kit!
Help your little scientist learn with exciting. interactive science kits from Smithsonian, Toysmith and more. Chemistry kits are a classic choice that let kids create colorful, foaming concoctions. Choose a themed kit, such as one that lets your child create perfumes and bubbles, for an extra sense of accomplishment. Rock and mineral sets teach kids about geology, or you can use a crystal-growing kit to create your own stunning example. Some kits even let kids excavate their own gems or dinosaur bones. Send your budding biologist outside to collect specimens for a worm hotel, and use a sturdy children's microscope to take a closer look at plant and fiber samples. At night, help your child explore the universe by looking through a child-sized telescope. Overstock.com has high-quality science kits and toys available for every age and interest.
A wonderful project based kit to encourage creative exploratory thinking. I buy these as gifts.
I used this company when I was teaching to create centers in my classroom and encourage science project thinking. Now I purchase for grand and great-grand kids.
