Used only once for a friction and resistance experiment. It's a slightly more本格的な (本格的な: full-fledged, serious) set, like the eraser-flicking game that elementary school students play. The speed at which the cars move differs depending on the material of the car body. Main body x 8 Starting platform x 2 Ballpoint pens x 2 In the late 1970s, a supercar boom swept across Japan. Races using "supercar erasers" and the click-type pen "BOXY" were a popular game among children. Those who have raced with supercar erasers may have experience modifying erasers or ballpoint pens to make them go further or land precisely at a target. Therefore, "Super Friction Cup 2024 SEXY321" focuses on the sliding properties and grip of the materials, offering five different materials with varying ease of launching, and designed the body of four car models: STRINGER, EPIC, XENO, and YARE. Choose your favorite car and race while experiencing the friction characteristics of plastic materials, not through numbers, but through "feel." ● Supercar Materials Prime Polypro® Polypropylene, which accounts for more than half of the plastics used in automotive parts. It balances lightness, high strength, and cost, contributing to the weight reduction and extended range of automobiles. LUBMER® Ultra-high molecular weight polyethylene. It has excellent sliding performance and is used in applications requiring wear resistance, such as gears and window sashes. This will be a very slippery car. Collaborations ・Nagaoka Mold Co., Ltd.
