1 The air we breath is a mixture of gasses: primarily nitrogen, oxygen, & carbon dioxide. 2  So, the air you blow into a balloon creates pressure that causes the balloon to expand (& this pressure is generated as all the molecules of nitrogen, oxygen, & carbon dioxide move about & collide with the walls of the balloon).
Bravo Sports Corp. in Santa Fe Springs bought Sector 9 in La Jolla on undisclosed terms. Bravo makes scooters, skateboards, helmets and other sporting goods under about 20 brands. Sector 9 makes skateboards, surfboards, snowboards, gear, and accessories under three brands, and had been owned by Billabong International.
The first skateboards started with wooden boxes, or boards, with roller skate wheels attached to the bottom. Crate scooters preceded skateboards, having a wooden crate attached to the nose (front of the board), which formed rudimentary handlebars. The boxes turned into planks, similar to the skateboard decks of today.he first manufactured skateboards were ordered by a Los Angeles, California surf shop, meant to be used by surfers in their downtime. The shop owner, Bill Richard, made a deal with the Chicago Roller Skate Company to produce sets of skate wheels, which they attached to square wooden boards.
