What if you could control the flow of slime across a table? What if your Silly Putty could curve toward, then stick to the side of the refrigerator?
I just read about magnetic putty on Instructables, an online network for tinkerers and inventors. Looks like tons of fun. I thought that teachers might want to make some for demos and class activities. Also, the comments at Instructables offer many ideas for potential science fair projects.

Check with a high school chemistry teacher for some safety suggestions, but if the kids do not ingest the putty, wear goggles and masks (bandannas or scarves are fine) so they do not get iron dust in their eyes or breath it in, and you get the coarser powder, it should be plenty safe for elementary and junior high kids. (Read this essay of mine--I taught HS chemistry for years--about Elementary School Science Safety; follow the links to other essays on safety.)

The need for the safety precautions are especially important if students mix their own. Warning, fine iron dust is flammable and a spark can set it afire. If you buy the iron (II) oxide from a chemical supply company, the finely ground powder must be kept away from an open flame and any sparks. Keep it out of drafts as it blows into the air easily.
In fact, this iron powder is one of the chemicals that teachers blow into candles to make the flame get larger and brighter and sparkly.
I would love it if you, Teachers, had your students suggest experiments with this silicone putty + ferric oxide. Tell me about it in a comment--or have them do so. If you do try it with slime, I would like to know about that, too. I would really like to have a list of science fair ideas in a set of comments.
You can get the needed chemicals from Amazon.com.
Don't forget your safety supplies!

Hello,
great post!

how to unlock iphone 4
i have a problem with my internal HDD. When this all happened, i was playing a game online. I got a Virus Worm and i shut down my computer and reformatted my HDD and put windows back on. I had a secondary HDD in for back-up purposes. so got windows in and put everything back, but i then noticed that my computers performance went down drastically with my main HDD, I could not copy anything i had onto the back-up drive and once i did it was so slow to copy the file. Once i had all the files on the back-up drive, i decided to start from the back-up drive with windows. Same applied. It was really slow with the reading-and-writing. i decided to take the secondary back-up drive out and boot from the main HDD. Everything seemed to be running smoothly i checked the main HDD Temperature with HD tune. The drives temp was 37 degrees Celsius, and the drive went to normal temperature of 43-44 degrees Celsius. I then decided to plug in the secondary HDD and leave it on for a day. the temperature went from 43-44 degrees to 47-48 degrees Celsius. So my guess is that the HDD drives are getting way to hot, and i am getting what seems like bad sectors in the drive, but it has never done this before. I have always had my back-up drive in ever since i got my main HDD. I can't place my finger on what is wrong with my drives. Once the main HDD is lower temperatures the drive seems to be performing better. but its normal temperature is 43-44 degrees Celsius and i still have some problems with reading and writing then. Can someone tell me what has happened please. I dont know if it was from the worm virus or if the temperatures are getting too hot (but has never done this before) can someone tell me what to do. I have changed the line leading into the motherboard as well, and that seems to have no effect. i even swapped the board lines between the CD drives and the HDD drives, no effect on that either. can someone tell me what is going on, i have ran out of options.

Preparing for a large move? It's really a very stressful time, from determining where you are going to live and hiring a moving truck to packing up all your belongings in cardboard boxes. With so much going on, you most likely have a great deal in your thoughts. Throughout the procedure for moving, just ensure that you do not sacrifice the security of your self as well as your property. If you do not keep your safety in your mind while moving, your belongings might get lost or stolen, or your individual safety can also be threatened.

Otherwise, a burglar could make use of the proceed to break in and just take whatever remains.
Once you get access to you new home, your first three steps should be turning on the electricity and water services and changing the locks. These should be achieved just before moving day if at all possible. Even though you know the prior occupants and think they're trustworthy, always change the locks when getting into a brand new place. You merely never understand how many copies of the important thing are available, and it is easier to be safe than sorry. Exactly the same applies to changing the codes for alarms and security alarm systems.
When the boxes are unpacked, you've still got several essential security alarm tasks in front of you. As you settle in, consider methods for you to make your residence safer. Have a survey of the house to inspect all the door and window locks. Determine if you will find any broken windows or old ones that would be forced agape. Consider replacing the leading door with one that's thicker and less inclined to get kicked in by an intruder.
Security alarm goes beyond checking the health of existing security features. What are the bushes that have to be reduce to get rid of potential hiding spaces, or dark places looking for extra security lighting? What are the outdoor security lights at all? How about security alarms on the windows and doors? Relocating is time for you to install these critical security alarm features. Do not wait until you've settled in and be complacent before considering potential security upgrades. Actually, many families would rather have many of these devices in position before ever spending a night within their new home, to greatly help them feel at ease whilst getting used to sleeping within an unfamiliar room.
