Duncan - The Drinking Bird
A classic novelty item!
- A simple scientific wonder
- Using principles of thermodynamics
- With constant bobbing motion!
Duncan the Drinking Bird is a fun desktop companion and classic novelty item.
Fill a glass with cold water and submerge his head in the water getting it completely wet.
Place Duncan near the glass and he will continue to bob and dunk his head into the glass all day long!
It appears to be magic... But it's actually the principles of thermodynamics in action!
Keep a full glass in front of him and he will drink all day!
This is not a toy.
Drinking glass not included.
Recommended for ages 8 and up.
