During the summer before freshman year, I wanted to brighten up my Fourth of July. One of my first inventions was turning a cheap remote-controlled truck with flashing lights into a firework-launching tank. I disassembled the chassis, removed the lights, and redirected the wires into a lightbulb filament. I attached a metal pipe to the front and rewired the circuit. I grabbed some cardboard and built a new camouflaged exterior. On Independence Day, I loaded it with a firework, maneuvered it into position, and turned on the "lights." The filament glowed red, causing the fuse to light, and sparks burst out of the barrel. Witnessing the successful culmination of my work was thrilling, and it motivated me to invent more.
