“FLAT OF EXPERIMENTS FOR FAIRS OF SCIENCES?

This he is a simple one:
THAT IT IS NEEDED
OriginalDustCover

Paper of silk, fine cardboard, glue, pencil, scissors, etc.

HOT-AIR BALLOON

Since one becomes

1. - To the construction and assembly of this globe of paper, we will have as starting point the group that forms its faces, drawn in better paper or a copy of the same in cartoncillo to natural size. The drawing that down we showed of the group for being its symmetrical sides its half will only be necessary. In order to make the group you can extend it until the size that you need. The group becomes in a fine cardboard.

The paper that we will use must be thinnest and light possible, it is recommended to use the silk paper.

2. - We will extend the average group on the table, and will stick so many sheets of paper of silk as they are necessary to cover the size with the same.

3. - Previously we will have decided as to place the colors of showy form to secure good results.

4. - The obtained leaves we will double them throughout its mean line and we will pile up them of uniform form, placing the leader lines of all to the same side, holding them with great click or any type of clamp.

Once piled up, the group upon form is placed that serves as guide in the cut of the bands.

5. - The cut of the paper bands, with the form of the group is possibly the delicate part but of the assembly, on its cleaning will depend the aesthetic one of our globe.

The cut we will do it with scissors having tried the greater uniformity in the same. It is worth the pain to test some in loose papers to secure a little practice.

We separate the cut bands leaving two of opened them, first and it completes and doubled it the rest of the same.

For the patch we will follow the following steps:

6. - To open the first double leaf and to place it on the table without it takes air, happening the hand exceeds she will adapt totally to the board.

7. - To place average band without opening on the right part of first, sticking with a fine thread of glue the outer edge of the two first placed leaves.

8. - To place another average band on the opposite side and to come in the same way that the previous one.

9. - Successively to stick to left and right so many bands as compose the globe, except the last one that will serve us to close it in the same situation that first, securing in both parts a “system of accordion?. In the case of a normal globe of six bands we would have: first opened in the part inferior, two doubled to right and two doubled to the left, and opened in the part a superior.

10. - To review you fold them intervals, that do not have to go patches, so that the rest of glue have not united them, and if so to separate them with well-taken care of before the glue dries.

11. - To let dry enough time.

12. - Finally we have left to place the metallic earring in the mouth inferior of the globe, which we will do doubling some eyelashes of the same paper, in the final part of the mouth, according to is explained in the figures. The earring that will have a diameter of 15 to 25 cm., provided to the size of the globe, will be necessary to unite it, by means of a suitable glue or weld.

13. - To verify that zones opened in the line of patch do not exist if so repegarlas. This verification will be made easily swelling the globe with the hot air of a hair dryer.
