Hydro Calculator!

Kids will amaze their friends with this very unique 8-digit calculator. No replacing batteries, it runs on water! Or juice, soft drinks, whatever you want to try. This amazing environmentally friendly calculator actually runs on water or other electrolytic fluids and is pollution-free. It's not just any old educational toy; it's a fully functional calculator!

How does it work? The internal converter extracts electrons from the fluid molecules and provides a steady stream of electricity to generate power. Instructions (in 5 languages) and a "Fuel" Applicator are included.
