crane game

Easy!! How to make a three-pronged claw crane game!
crane game

The claw machine, a popular attraction at arcades, has recently started appearing in places like thrift shops and supermarkets as well.

This project is a bit elaborate, but using thick graph paper makes it less likely you’ll make measurement mistakes.

Draw the parts on the graph paper, cut them out, and assemble them.

Making the claw with three prongs, like a real claw machine, will add more realism to your piece.

It’s the kind of summer vacation craft that would likely draw attention if displayed at school.

levitating top

Fun Science Experiment: Let's Make a Levitating Neodymium Top
levitating top

Neodymium magnets are used in a wide range of applications, from watches and mobile phones to medical devices.

Let’s use these neodymium magnets to make a mysterious top that levitates in midair.

Line up several neodymium magnets with their poles facing the same direction and take advantage of the repulsive force with the top.

It takes some ingenuity to adjust the positions of the magnets and the top.

But once adjusted, the top will float while spinning in the air.

Investigating why the top doesn’t stick to the magnets arranged below it, or measuring how long it spins, can deepen your understanding even more.

This makes a great project for summer crafts, independent study, or experiments over the summer vacation.
