## Description

Once this timeless classic starts drinking he won't stop! Just put a glass of cold water in front of him, or her, dip Drinking Bird's head in the water and release it. Drinking Bird will bob back and forth while drinking away! It keeps bobbing and drinking for hours. Please note this product is not a toy and is not intended for use by children under age of 8. The glass tube contains methylene chloride and may permanently stain clothing and other surfaces. Do not swallow liquid or allow to come in contact with eyes or skin. Non-flammable. Keep away from flame or other heat sources. WARNING: CHOKING HAZARD - Small parts. Not for children under 3 years.

Review: I used to maintain my one of these as a kid about 50 years ago. So glad they are still around. Works on such clever balance of the elements physics, temperature, pressure and evaporation. Great talking point for adults or kids to understand what is going on. FYI, the when the fabric in the head is wet it evaporates and cools the top bubble where the head is, this causes the air inside to shrink in simple terms which draws the liquid up from bottom bubble, which after a while causes the centre of gravity to go to head then the bird tips and takes a drink (which keeps the head wet), but when it is horizontal the liquid falls back down the straw tube body back in the base and it all starts again as when upright there is a vacuum again... etc. Very cool whoever thought of it!
Review: Was a gift - They loved it. Set it up and it works great!
