Attempts to create a real aircraft in the form of a saucer have been undertaken by scientists from different countries more than once. All such designs, even if they worked, turned out to be impractical. But you can build a working model of a flying saucer at home.
Instructions
Step 1
Take two lightweight but sturdy plastic hoops. They should be the same in diameter (about a meter). Place them one above the other at a distance of about thirty centimeters. Fasten them together with a series of lightweight plastic or wood planks. You should get a "two-story" design.
Step 2
Wrap the planks with several layers of wide tape to form a solid, low cylinder. Cover the bottom of it with plastic wrap, which is also fixed to the walls with tape. Put a light battery at the bottom, to which connect several LEDs through resistors. Spread them evenly around the perimeter so that they point down. It is these "rings of luminous dots" that have the stereotypical flying saucers in science fiction films.
Step 3
Purchase as many helium balloons as will fit in the cylinder. Place them there and on top also press down with a layer of film. Make it easily removable, for example, with clothespins located on the upper hoop. Tie the resulting structure to hooks stuck in the ground on three or four light, but strong threads so that it hangs horizontally in the air.
Step 4
As the helium balls leak out, the "flying saucer" will gradually sink to the ground. To start it again, remove the old balloons from it and place new ones (or refill the old balloons with helium). Before restarting, if necessary, change the battery in the "illumination", otherwise the toy "flying saucer" will not look like a real one.
Step 5
If you wish, use this model as an advertising structure. In this case, the power cable for the backlight can be run along with one of the threads securing it to the ground. It is also possible not to install any light sources inside the "plate" at all, but to put an advertising image on its bottom and illuminate it from the ground with a directed beam of a searchlight.
