Will the bird sit on the match?
For the experiment you will need: clay, one big match and a few small ones, as well as a wire. For starters, blend a plasticine with a bird like the one you see in the photo. Eyes and feet make of fragments of small matches.
You have a wonderful birdie. But can you put it on your paws now? Does the bird fall without balance?
Step 2: Do you think you did something wrong? Or maybe the bird just needs to be put on a big match, so that it's cozy, like on a branch? Does this sentence seem particularly unreasonable to you? Do not rush to draw conclusions and angrily turn off the video. You have to learn the secret of incredible dexterity! You not only sit the bird on the branch, but you can even make it dance! And the bird will not fall! You are ready? Just do not pull your hands behind the glue!
Step 3: Roll a large ball out of plasticine and fasten it to one end of a short wire, as shown in the photo.
Step 4: Insert the other end of the wire behind the paws into the bird's body at a slight angle, as shown in the photo.
Step 5: Now put the bird with the paws on the match. You should know that the easier the ball is under the bird, the longer the wire should be. If the bird tilts, pick up the wire of the desired length and, if necessary, change the angle at which it is bent. So with the help of simple experiments, you can get the bird to stick to the match very steadily.
Step 6: Here's how it looks from different sides.
Step 7: Now even if you quickly move the match forward and backward, the bird will not fall, but will only start to sway, as if dancing.
Step 8: How could you become so clever so quickly? Here, of course, it's not about magic and not in a long training. The whole secret is that the center of gravity of our system lies below the fulcrum. That is, the point to which the weight of the system is applied is located below the point on which it rests.
