S3E9 Engineers vs Custom Go Kart Racing

CrunchLabs product designers are given just 24 hours to design, build, and race their own custom go-karts. The challenge blends engineering expertise with creative problem-solving, but there's a catch—each team must also incorporate a surprise twist into their build. The clock is ticking, and only the most clever, durable, and surprising kart will take the checkered flag.
