Be Steam-Punctual!

How did it get so late so soon?
- Dr. Seuss
If clocks and time fascinate you, this Mechanical DIY 20-Minute Timer will be the perfect addition to your desk, table, or countertop. Set it for anywhere from 1 to 20 minutes and this chronograph will then count down with a gentle tick-tock sound, making a louder noise when the timer is up. Simply assemble the 107 laser-scored pieces according to the included instruction booklet and you're ready to go. The timer is operated via an efficient roller pendulum through the power of gravity and rubber bands. The completed kit also includes an adjustment system on the back for fine tuning.

This beautiful and useful decoration will adorn any house in vintage style. Simply set the timer, start the pendulum, and watch it count down. Made from premium grade plywood, the 107 pieces are scored and ready for you to punch out and put together. It's a fun project that requires no tools (although you may wish to have a craft knife handy and a small hammer to help things fit). We recommend that little kids have adult supervision, to help understand instructions, provide brute force, and to keep the smaller pieces from snapping. Once assembled, test this chronograph against a regular clock to make sure it's accurate, making small calibrations as needed. Tick tock!
