"Flogos"—floating logos made from a mixture of soap-based foam and buoyant gasses—slowly float above event sites after being deployed by a company technician.

The company custom-manufactures logos, which are then deployed from any of three different size machines; the larger the machine, the more complex the logo can be.

The logo stencil is usually ready the day the order is placed, the company says.

The product is 100 percent environmentally safe, the manufacturer says.
