Scitoys.com has a cool writeup on how to very easily assemble a hydrogen fuel cell in all of about 10 minutes. Just need a popcicle stick, battery clip, platinum wire and a glass of water.

Here’s a nifty little flash application from NASA featuring Buzz Lightyear allowing kids (elementary) to participate in a variety of science activities related to the space shuttle and international space station.

So I’ve had some discussion with a number of teachers using a variety of mothods to share files with others, both within and outside of the school district. Some are using email, some traditional file sharing, some using online service and others still posting to web server space. I really don’t do a lot of file sharing, but when I do I always have access to web server space for ftp or http download, but the average educator doesn’t have that luzury. So I’ve had my eyes open for a decent free service that would be one I’d recommend for this purpose and I’m finally settled on MediaFire.

MediaFire offers UNLIMITED storage, allows file sharing, is completely free and doesn’t even require a login. If you do create an account its easier (obviously) to manage your documents, but if you are in a situation where you need to quickly share a file with someone and would rather not attach it to an email (let’s say its a big file) simply visit MediaFire and upload the file - it’ll give you a link code and even an embed code to slap it on your webpage or wiki or blog. Now just create an account by providing an email and password and viola - your document is archived for future easy access. The only limitation to this excellent resouce is the 100MB upload limit. That means you can’t upload files larger than 100MB, but come on…not many of your documents (at least at this point) are going to be larger than 100MB unless its an entire album or a long video.

But wait…there’s more. MediaFire allows you not only to share individual files with other people by emailing a link or embedding within a webpage, but you can also create folders for your files and share the entire folder contents the same way. Very cool.
