More Dangerous Kids

My car had a flat tire. When you get a flat tire, you might as well make something useful of it – right? As I was jacking the car up, I had a great idea. Use this for one of my “Spoof Science” videos. The only problem is that this takes a ton of work…

Kids like demos

Sometimes I get asked to do some demos for kids. I like this, it is fun. This week, I was asked to do just such a demo. Kind of as a historical record, I am going to document what I did. The audience It is always important to think about who you are talking to.…

I got tired of attacking ESPN Sport Science. Well, tired of attacking might not be the best term. How about, attack in a new way (here are my older Sport Science attacks). Check out episode 1 of Spoof Science: A couple of notes: Watch it youtube if you want the HD version Making videos takes…

ScienceBlogs.com is running “Ask a Science Blogger”. The basic idea is that you, the reader, get a chance to ask questions to us, the bloggers. You can either post a comment in the link above or send an email to . I would like to go ahead and answer one of the questions already posted.…

How do color filters work?

So you have seen these color filters (or gels as they are also called). When you look through a red filter, everything looks red. What do they do to the light? I am not going to tell you the answer. However, I will show you some examples so that you can figure out the answer…

Why is it dark inside?

This was a great question. When you come inside after playing in the sunny outside, why is it so dark? Simple answer: because your eyes are smart. When you are outside, there is a lot of light. Really, it is too much light. To compensate for this, your pupils (the part of your eye that…

A demo for the color black

What do you see when you are in a completely dark room with no lights? That is a great question to ask. It can bring out some interesting ideas. Anyway, here is an easy demo to show the color black. The basic idea is to build a box that has a small opening. Here is…

I have already indirectly talked about this before, but I see it more and more. Say you have a show. It has to be more than entertaining, it has to educational. How do you make things educational? Describe the physics behind the concepts – right? Fine. How do you explain stuff? It’s simple. Just make…

Tom and Jerry, or Fetch! with Ruff Ruffman? Answer: Tom and Jerry. What? Yes. The reason: Tom and Jerry has bad physics but does not pretend like it has good physics. I know this is probably going to “type-cast” me as “that guy that keeps attacking Ruff Ruffman.” Soon to be followed by “Leave Ruff…

I just got back from judging elementary level science fair (this is like kids in 6th grade or something). Here are some quick notes in no particular order. Please, please do not have a 20 item list of supplies that you used on your board including things like thumb tacks, tape, paper and poster board.…
