Invention Riddles for Future Innovators

I lit up rooms with a glowing wire. Flip me on and I never tire.

I send voices through invisible waves. Hold me close and chat in caves.

I roll on four, powered by spark. Fill me with fuel and drive till dark.

I take to the sky with propellers twain. Brothers built me to paddle the air lane.

I piece together parts with coding art. Print me in 3D to play the smart part.

I crunch numbers mini-sized. Fit me in pockets once super-sized.

I map the stars from space so high. Take my pictures to learn the sky.

I brew caffeine in drips so neat. Pour me bold for a morning treat.

I whistle with steam down iron rails. Toot my horn for mail in pails.

I paste pages with wear-and-tear. Snap my teeth to keep them there.

I’m a tiny chip that stores your song. Plug me in and sing along.

I cool your home with spinning breeze. Twist my dial to set degrees.

I track your steps inside your shoe. Sync me up to health stats too.

I clean the floor with sensors keen. Tap my button and I sweep unseen.

I carry humans to lunar dust. Strap in tight — exploration’s a must.
