About This

• BUILD TWO DISPLAY-WORTHY PHYSICS PROJECTS: Create a balancing bird that rests on its beak and a 4-in-1 space mobile featuring a Sun, Moon, comet, and star. Kids use their 3D pen to make two real sculptures they can proudly display.
• EXPLORE BALANCE, GRAVITY, LEVERS, AND TORQUE: Hands-on experiments introduce center of gravity, static and dynamic balance, lever arms, and torque through building, testing, and adjusting each creation.
• 60+ PAGE FULL-COLOR PHYSICS GUIDE: Step-by-step photos, child-friendly science explanations, troubleshooting tips, Think Like a Scientist prompts, and parent notes help kids complete each project successfully.
• COMPLETE PROJECT COMPONENTS INCLUDED: Includes a separate template booklet, reusable PET tracing sheet, wooden bird stand, acrylic rods, fishing line, washi tape, feathers, pony beads, and other experiment materials. A 3D pen and filament are not included.
• MADE FOR 3D PEN USERS AGES 8–15: Works with most standard 1.75 mm PLA or PCL 3D pens. No 3D modeling experience or app is required—kids trace, fill, assemble, experiment, and display their finished work.
