Questions & Answers
Question : I need to know how long to leave rocks in a rock tumbler.?
i have a science Tech rock tumbler that came with different types of powder. Course grinding powders and polishing powders. Each powder took different lengths of time to work. Unfortunatly i have now lost the instructions that told me how long to let the powders tumble. Can anyone tell me how long to leave each powder in?
Answer:
These instructions may be for tumblers larger than yours - http://chemistry.about.com/library/weekly/aa011803a.htmIf you do not get an answer from someone who has the actual instructions, look on the box it came in for an Internet address. Tell them you lost your instructions and they should send you a copy.

what is a science experiment with a rock tumbler?
Answer:
Rock Tumbler Experiment: compare different grits that polish stonesFor example, compare using Bon Ami instead of regular tumbling gritBon Ami..You can pour your waste water down the drain. ..You don't have to check as often...You are less likely to ruin your beads.Tumbling grit..Takes less time.http://ornamento.wordpress.com/2009/05/14/sanding-polymer-clay-beads-in-a-rock-tumbler/

Question : Where to buy unpolished rocks?
Does anyone know where I can buy unpolished rocks? I just bought a rock tumbler for a science project and I need to know where I can buy these rocks. Hopefully they can be found at a local store? Thanks.
Answer:
You can purchase them at most hobby shops, but unless you want to polish some rare gemstones or soomething, I have to agree with the others.... just collect them from outside.

Question : Edu science rock tumbler instructions?
I lost my rock tumbler instructions and I don't know how long each powder thing needs to be with the rocks....Here's what it looks like(i think it might help):http://images.buzzillions.com/images_products/03/79/edu_science_rock_tumbler_toys_r_us_reviews _608506_175.jpgMay you guys send me the time limits for the powders....type them in your answer perhaps?
Answer:
Wow that is a nice one you have, it is probably quieter with the plastic cover. I use to tumble my rocks either in the basement or in an empty drawer in my dresser to sort of block out some of the noise. The one I had when I was younger was probably the first do it yourself old Smithsonian rock tumbler. I'd say that was probably one of the best gifts that I have ever received. Well, first, you put the bag of rocks that you want to tumble in the tumbler. Make sure it only fills the barrel 2/3-3/4 full or you may have to extend polishing time.then, usually you use the thickest to the thinnest grit in that order. You put the thickest grit in first and let the rocks tumble from 7-10 days (for optimal polishing). You will do this for each grit you use.Make sure there is no grit transferred from one step to the next.You can e-mail me, via my profile, if you have any questions.

Question : Are the planets gradually becoming perfect spheres?
Just as a rock becomes a gemstone in a rock tumbler, a rough or ridged object becomes smooth or perfect in shape after being exposed to the same constant force for a long period of time. Is this the case with the planets in our solar system? As the celestial bodies orbit the sun they are exposed to the same movement year after year. By looking at the pictures of the planets in a science book or from the readings of a satellite, you can see that they indeed are spherical. When the big bang occured they could not have been perfectly-shaped like that. Therefore, they must be gradually turning into perfect spheres, correct?
Answer:
The increased centrifugal force at a rotating planet's equator can make a planet bulge around the middle. Atmosphere and oceanic friction slow down rotation slowly but surely over geologic time, though.Then there's internal forces within a planet that affect the shape of the surface, but the energy that makes the core hot enough to do all that has to diminish slowly but surely, it seems. Cosmic collisions between a planet and an asteroid here or there can add energy back, but in the grand scheme I think it's a general rule that they get rounder.

Question : Does anyone know how to make a rock tumbler?
okay so i need to make seaglass in like 3 days for a science project. i was wondering if anyone knows how to make a rock tumbler that would be quick and easy to make or if theres any place with a cheap rock tumbler i could buy. i would put the glass in the tumber and fill it with water and i need something im only 14 so i need something easy to make.
Answer:
Yeah what Brian said is a cool idea. Don't be shy to walk into the local jeweler place. They probably would get a kick out of it anyway to help you get started in polishing.Another idea is maybe your school or high school biology/science teacher might use them? Maybe they'll let you use one after school.I just searched youtube for "tumbler" and alot came up. This gave me an idea for a cheap and easy tumbler with common household items. And I might try this myself to see how it works. I've always wanted a tumbler but I have never had the need for one.Have your dad help you with this. I hope he is handy with some tools and has a hand drill.Take a big plastic round mayonnaise jar. Get a machine threaded screw that is about 2 inches long and about 1/8" diameter--one that can stick into a hand drill. (Like when you put a drill bit in the hand drill)Drill a hole in the center of the lid the size of the screw.Slide the screw through the hole from the inside, with a bigger diameter washer to grip onto the lid. On the other side of the lid, use another washer and then a lock washer and nut. Tighten down real good.If your mom has a rolling pin or two, rig something up so the end handles rest on something securely. The jar will rest in between them, so the jar can spin freely.Then tighten the hand drill chuck on the screw that is sticking out of the top of the lid. If your hand drill trigger can lock into place and stay on then you can set it and forget it. Just keep it real close to your bench top so the handle touches the bench top and doesn't rotate.This could work--something quick and dirty for you.But if you can get a motor, and handy with some wood and a saw, you can make something more sturdy and something to last.But this should give you an idea of things to try.Good luck! Let us know how it goes. :-)
