现在置身于40年前发明了Slime黏质物的实验室，克洛斯科瑞提和他的团队打造出了玩具所需的各种化学成分，比如芭比数码指甲打印机所用的化妆品级的墨水，这台打印机能直接在指甲上印出照片来。他近期上市的产品之一是风火轮车模（Hot Wheels Car）制造机。它能让孩子们把融化的蜡注入一个车身模具，自己做出车模。它已经通过了一位严苛批评家——他外甥的考验。他说：“很幸运他喜欢这玩具。”

Jason Kroskrity was studying epidemiology at UCLA until he realized that while it satisfied his love of data and science, it wasn’t tapping into his creative side. “The idea of not having a creative piece as part of my profession started to scare me,” Kroskrity says. He left school and was recruited to Mattel by a high school friend in 1998.
Now in the lab where Slime was born 40 years ago, Kroskrity and his team come up with the chemical components of toys, such as the cosmetic grade ink for a Barbie digital nail printer that paints photos right onto fingernails. One of his most recent projects to hit the shelves is the Hot Wheels Car Maker that lets kids inject melted wax into a car body mold. It passed muster with a tough critic—Kroskrity’s nephew. “Fortunately he liked it,” he says.
