Baloane de sapun colorate

Rate this topic

Recommended Posts

Astazi am citit un articol foarte interesant:

http://www.popsci.com/popsci/science/0a03b...ecbccdrcrd.html

 

Va fac un mic rezumat dar eu cred ca merita sa cititi intregul articol.

 

Dupa o munca de 11 ani Tim Kehoe a reusit sa-si indeplineasca visul:

A realizat baloane de sapun de diverse culori care nu lasa pete in momentul in care se sparg.

 

Acest lucru a fost posibil datorita descoperirii unor vopsele care isi schimba structura prin frecare.

 

Sabnis's solution was to build a dye molecule from an unstable base structure called a lactone ring that functions much like a box. When the ring is open, the molecule absorbs all visible light save for one color

Interesant. Dar pacat ca nu mai suntem copii pt balonase de sapun care contin si vopsele.
