I'm a science teacher, will this make exciting clicking sounds for my class like the movies? Will it pick up cosmic/background radiation?

Yes! However if it starts "clicking" a lot your class is in for more "excitement" than the ever bargained for. Look for a bright flash in the distance first. Then tons of clicking. Then Jesus. :)

I would recommend it to you. The wide screen makes it ideal for movies, but the audio quality is not so great. I wouldn't say it's bad though, just the internal speakers are sub-par. Get a set of external speakers, and you'll be good to go. As far as school projects go, it's been able to handle all the projects I've used it for :)

All that we have used it for is to play some nature cd's such as a rain storm, crashing waves, gentle surf waves, babbling brooks....etc. I have not noticed any background noise with this type use.

It does make an audible click. Maybe slightly softer than a regular mouse, but still noticeable. I'm a grad student and use it one of my classes. That class is pretty small (7 of us and the professor), so I am occasionally self conscious about the click.

You won't hear it at all. I just finished a presentation last week and everything worked really well (slides and laser). Excellent product.

You will hear a faint clicking sound. I use them in a school setting and I only notice it when I am close to the device.

yes - the "PSST" sound one would make (like trying to startle someone) works. Has to be loud though. we discovered this by one of my brothers trying to startle our cat. turned the tv off while my dad was watching. and back on, then off -- you can imagine we had some fun messing with my dad when he watched TV. Actually worked more consistently than the clapping we found

It works really well in a classroom. Record what is being said and review it later.

No it doesn't make any noises. It just has a laser beam when you press it. Works great for me.

That would depend upon which type of radiation you are referring to. This does measure electrical radiation, such as power lines and so forth. As to nuclear radiation, I don't know. If you have it near a power station it starts to go crazy. If I walk down the street where I live I get a few readings, then when I turn a corner where there are a lot of electrical power lines, TV antennas it goes nuts.

Probably not. however, you can hang it around your neck so it may work. I use it in my classroom with 25 5th graders and I can hear it when I am within a few feet

The buttons do make an audible clicking sound. I'm not sure I would describe it as loud. It feels good and provides good tactile feedback. The clicking would not be audible to your audience unless you held it in close proximity to your microphone.

It makes a click-clack sound that is not loud. For details, see my answer to the question: "Does this make noise?..."

Naah, I don't think that it would. Mainly bangs and large vibrations.Good luck!

On a scale of 1 to 10, I would say this is about a 6. You can definitely hear it as long as there is not a lot of noise in the background. My daughter has used it on two class projects and it works perfectly.

It does make some clicking sound but it's not that noticeable to me. If it is loud enough for you and it is bothersome you should really try to get a replacement as it may be defective and will soon fail.

it will make a small clicking sound kind of the level of sound like typing on your keyboard but quieter. there are individual plastic links and if you click the tangle quickly, then the pieces kind of link-link (make a small link clicking sound of plastic touching plastic). Other than that- no bells, whistles or anything.
