Amazon has the Bedol Little Squirt Blue Water Clock for just $18.95!

What this does and why you need it:
This clock runs entirely on water and needs just a splash (every 6 months) to get going! Set a daily or hourly alarm and have a 12 or 24 hour clock. No batteries or electricity are required, so you never need to worry about missing your alarm. Ions in the water are converted into clean energy power making this a great gift for the energy conscious!
