I made a simple mechanical claw using two paper cups and a plastic straw.One of the cups was cut lengthwise into four equal parts, forming a flexible claw with four gripping segments. These segments act as grabbers that can close and hold small objects.A straw was glued to the bottom of the cut cup and…

In this project, we create a rotating flower powered by a stream of air. I made a three-dimensional decorative flower from colored paper. The flower is attached to an axis. A cocktail straw is used as the axis. Cardboard blades are fixed to the lower end of the straw. The blades are placed inside a…

In this craft, we will glue a windmill out of cardboard and install a small motor to rotate the blades.‎The motor will start rotating when a switch installed on the side of the windmill is turned on.‎We will cut an opening in the roof of the windmill through which coins can be dropped inside. ‎All…

In this craft, we will make a clown with a magic nose: as soon as you insert a coin, the nose lights up.‎‎The clown’s nose is made from an LED. It is connected to the positive terminal of one battery and the negative terminal of another. When a coin is inserted into the clown, it…

This craft works by transmitting motion through rigid linkages.When we pull the tubes downward, the motion is transferred upward to the kitten’s head and paws.The holes in the cup act as guides, directing the motion so that all parts move together.

Today we will make a frog with a protruding tongue.This craft is based on the principle of excess gas pressure in a closed volume.When air is blown through the tube, the pressure inside the flexible chamber increases,causing it to deform and unfold, mimicking the extension of a frog’s tongue.

In this lesson, we will make a fluttering butterfly. The craft is based on a telescopic linkage mechanism made of two tubes: one acts as a guide, while the other serves as a moving rod that transfers motion to the wings.

In this video, we will learn how to make this puppy with a swinging head.This craft is based on the principle of a lever, which we can observe in real life, for example,in the control mechanism of an excavator’s boom and bucket.
