Description: In this activity, students test a slingshot-like device that throws a mass causing the car to move in the opposite direction. Unlike in the original pre-smartphone instruction, we load the car with a smart phone running phyphox in acceleration measurement. Hence, we have the Newton car loaded with more mass! Materials and Tools: • 1 Wooden block about 10 x 20 x 2.5 cm  • 3 3-inch No. 10 wood screws (round head) • 12 Round pencils or short lengths of similar dowel  • Plastic film canister  - (ha ha, this will be a challenge ;-) • Assorted materials for filling canister (e.g. washers, nuts, etc.)  • 3 Rubber bands  • Cotton string  • Safety lighter  • Eye protection for each student  • Metric beam balance (Primer Balance) • Vice  • Screwdriver  • Meter stick • Smartphone, cell phone Refs. 1.
