How to make a seismometer

How to Make a Simple Seismograph: A Summer Science Project You Can Still Do in Time

Why not try making a seismograph using everyday materials? The word “seismograph” might sound difficult, but it’s actually easy to build.

A seismograph mainly consists of two parts: a pendulum that serves as a fixed point and a recording mechanism.

For the pendulum, fill a cup with clay, insert a bamboo skewer as the axis, and hang it from a support made of disposable chopsticks using a hook and thread.

The recording part can be made from a toilet paper roll with a bolt through it and a ballpoint pen.

The base of the device can be anything, so try to find a wooden box that can hold the setup.

repeating saline solution

Perfect for a summer vacation science project! ~Repeating Saltwater~ [Buntoku High School]

Let’s try a summer break experiment using everyday items like cups and saltwater.

Make a hole in a plastic cup filled with saltwater at your preferred concentration.

Place the saltwater cup inside a larger cup filled with plain water.

You’ll notice something curious: the saltwater will flow out of the hole and then stop, and after a while it will start flowing out again and stop once more.

It could be fun to experiment by changing the salt concentration or the number of holes in the plastic cup.

Just watching this setup is interesting, but there’s also a proper explanation for what’s happening.

Try to think about that answer, too.

Bamboo Speaker

[DIY] How to Make a Bamboo Smartphone Speaker for Zero Material Cost

Let’s try making a speaker that plays sound from your smartphone using bamboo.

It takes advantage of bamboo’s tubular shape to naturally amplify sound through resonance.

If you have a bamboo grove nearby or can get hold of bamboo, this is a perfect summer vacation craft project.

Cut the bamboo, peel off the green outer skin, and lightly scorch the surface with a gas burner.

Charring it with the burner turns it black and gives it a beautiful finish.

Cut out the section where the smartphone will go and drill holes on the surface.

The key is to be careful not to crack the bamboo.

It’s a detailed project, but that makes it all the more rewarding, and you’ll end up with a one-of-a-kind creation.

Let’s make a professional kalimba

Let's make an authentic kalimba!

It would be fun to make a genuine musical instrument using items you can get at home improvement stores or online, wouldn’t it? This time, we’ll introduce a handmade, authentic kalimba.

A kalimba is a traditional African instrument played by plucking thin metal tines attached to a box or board.

Using a box or board allows the sound to resonate.

Let’s try making one by building a wooden box and attaching thin rods.

Specialized kalimba metal tines, called kalimba keys, are also available from online retailers.

Master the playing technique, and let your kalimba produce beautiful tones.

Experiment to make butter

Experiment to Make Butter – High School Biology Lab

Butter makes all sorts of foods delicious—spread on bread, melted over baked potatoes, and more.

Did you know it can actually be made with a very simple process? The main steps are to pour chilled heavy cream into a sterilized container and shake it vigorously for 15 minutes.

The liquid will separate and turn into solids—the solid part is unsalted butter.

Mix in salt, and you’ve got butter! Shaking for 15 minutes is surprisingly hard work, so it might be a good idea to do it while watching TV.

Let’s also summarize why butter forms in the first place.
