What powers the Clock With Water?
It runs on water alone, so no batteries or cables are needed. Ordinary water poured into the chamber starts a small electrochemical reaction, and that supplies the current for the digital display.
How long does one fill last?
According to the description, a single fill lasts for weeks. When the display starts to fade, you simply top up with water again and the clock carries on.
What size is it and what is it made of?
It measures 10 cm by 9 cm, so it fits on a desk, bedside table or classroom shelf. The body is transparent, BPA-free ABS plastic, which lets you see the water chamber.
What can the display do?
It is a digital clock with a large display and a choice of 12 hour or 24 hour mode. It is also described as an alarm clock, and the set-up is simple.
