Ghostly After-Image Effect

Filed under Science Experiments, Things To Do

No, there aren’t any ghosts!  But this does look kind of spooky. Would you like to see things when it’s totally dark?  This strange trick for your eyes only lasts a few moments, but it’s fun to do. Try it by yourself or with a brother or sister (or even Mom or Dad!)  It’s a […]

Clouds Come and Go

It’s always interesting to see things from different points of… time. Things that normally happen slowly can reveal surprises when sped up. We usually think of a cloud as a big fluffy white thing that floats along as a more-or-less “solid” object. Here we can see that they really appear and disappear, forming and vanishing […]

Seeing Sound

The sound we hear interacts with itself to form patterns we usually can’t see. Salt on a metal plate, and attached to a speaker, shows these patterns clearly. httpv://www.youtube.com/watch?v=s9GBf8y0lY0

Marvelous Magnets

This is a two-part project.  First, you need to gather what you need for the second part! You’ll  need a strong magnet.  If you don’t have one, a trip to the hardware store should provide what you want. Check your hardware store first but Lowes has a very good set of two strong magnets for […]

Mobius strip

You can, right now, make one of the most puzzling things in the world. Take a sheet of printer paper and cut a one inch strip from the long side.  Get ready to tape the ends together to make a loop but wait a moment. Before you tape them, turn one end over (180 degrees) […]

Iceland’s Volcano

Not many of us get to see a volcano up close and in action. While this new eruption has caused all sorts of problems with air travel, it’s giving us a good look at the power inside our planet. Watch closely for ripples that spread out through the smoke (good one at 17 seconds!) These […]

The Invisible Force of Magnets

Magnets are very cool.  Put them together one way and they’ll stick.  Turn one around and they’ll push apart. But did you ever really play with two strong magnets and think about it? Get two strong magnets.  Some Radio Shack and hardware stores have nice ones that are about an inch wide, two inches long, […]

The View From Space

It’s not until we get high above the Earth that we see how small and very precious our world really is. We live on the surface of the Earth, with our deepest digging and drilling only scratching the surface. There’s just a thin film of air to let us breath and, at the same time, […]

The Colors of the Rainbow

When light goes through glass at an angle, it spreads out into all the colors of the rainbow. You can do this easily at home yourself with a glass of water and a sunny window. In front of a window where the sun is shining, place a clear glass of water on the edge of […]

Static Electricity is Cool

This most excellent hairdo is thanks to thousands of volts of static electricity! Not to worry, it’s harmless.  Well, almost harmless as it can give you a pretty good good snap!   🙂 Did you ever get out of the car in the winter and get a shock? Yep!  That’s static electricity. In future posts, […]
