Then came the trays, which once again have become popular. Such gear for a bubble show is made by stamping. Stamped trays are made of sheet material. Then, under the influence of high temperatures, they are bent to allow the trays to assume a certain shape. They are often equipped with a beak. Now such trays are made in black; before they were brown. Pros: lightness and cheapness, cons: the fragility of stamped trays. Now many people think how to attach wheels to such Human Inside Bubble props, make them more convenient.
What should you look for when buying these trays? If the chosen material, that is, ABS plastic, is too thin, the tray may break. This applies to a material with a thickness of less than 5 mm. When stretched under the temperature, it can take a thickness of 1 mm in some places. This is not very good for the tray. Pay attention to this when buying.
Be sure to ask what thickness was the plastic before making the tray. If this tray cracks, it's very difficult to fix it. Glue won't help.
More often, trays made by stamping cannot be made larger than 85 cm in diameter. In fact, this tray will be a maximum of 83 cm. This feature is associated with machines making such trays. This is their maximum diameter capacity. For me, this is a significant disadvantage. I do not understand how to work with such a tray, for example, at a wedding. On a children's holiday, I like to place 3-4 people inside one bubble. With a tray of 85 cm in diameter it is almost impossible.
