How to Build a DIY Shake Table for Earthquake Simulations

Well, now, if you ever wondered how them big ol’ buildings shake when the earth moves, let me tell ya, I can show you how to make a little shake table of your own. It ain’t too hard, I promise ya. This here table will help you see what happens when an earthquake shakes a building. You can use it for a little science project, or just for fun. It’s like making your own mini earthquake right in your own house, and you don’t even need to be a scientist to do it!

So, first thing you gotta do is get yourself a flat file folder. You know, one of them folders you use to keep your papers nice and neat. You need something to stick your shake table to, so this will do just fine. Lay it flat down on a table or a sturdy surface. Now, you need to get the base of your shake table stuck to that folder. I just use some good ol’ tape, but you could use glue if that’s what you got around the house.

Next, you’re gonna build the shaking part of the table. You don’t want it too tall, so get you a ruler to make sure the height is right. You don’t want it sticking up too high, just enough so that it can shake and move things around when it gets going. Once you got the right height, you can start building the rest of the shake table. But make sure it’s sturdy. You don’t want it wobbling all over the place when you get it shaking!

Now, here comes the fun part: the motor! You can use a little ol’ DC motor for this. If you don’t know what that is, well, it’s just one of them small motors you might find in an old toy or a fan. You want to mount that motor so it can make the shake table shake when it’s running. But don’t just stick the motor on straight. You gotta put something off-center on the motor’s shaft. This thing, they call it an “eccentric mass,” and that’s what makes the shake table wobble and shake just like an earthquake does to a building. It’s just a little weight that makes the motor spin unevenly.

When you got your motor mounted and that weight on the shaft, now you can plug it in. Start the motor up, and watch your shake table start shaking. You can try putting different little structures on top of the table. Maybe make a tiny house out of popsicle sticks or some little toy blocks. Start the motor and watch how the shaking affects them. It’s like a mini earthquake, right in front of your eyes! If your little building falls down, don’t worry. It just means it wasn’t strong enough for the shake, and you can try again!

Remember, it ain’t just about having fun with the shaking. This here table helps you understand what happens to buildings when real earthquakes happen. You can use this simple table to test what kind of building designs hold up better, and what kinda ones fall apart. It’s a mighty good way to learn about engineering and earthquakes, all with just a little bit of stuff you can find around the house. So, get yourself a motor, a folder, and some tape, and make your own shake table today!

How to Build Your Shake Table

• Get a flat file folder.
• Use tape or glue to stick the shake table base to the folder.
• Use a ruler to make sure the table is the right height.
• Find a small DC motor and mount it on the table.
• Put an eccentric mass on the motor shaft to make it shake.
• Place little buildings or structures on top and turn on the motor to watch the shaking happen!

So there you have it! It ain’t too hard to build yourself a shake table. It’s fun, educational, and gives you a good look at how earthquakes work. Now go ahead and try it out, see if you can make the strongest little building around!
