To Whom It May Concern
Surbhi Verma, a 2nd
year B.Tech. (Engineering Physics) student of Delhi Technological
University, worked under my guidance this summer for a period of 40 days from 16/06/2013 -
26/07/2013 on a project entitled "A table top experiment to make flowing soap films". In this
project she developed a simple vertical arrangement to make a stable flowing soap film based on
designs available in the literature. She investigated the suitability of various soap and surfactant
solutions for the soap films. At the end we were able to come up with a compact and easy-to-set-
up lab demonstration that could be used to show the properties of thin soap films and study
interference and turbulence patterns.
Over the period of the project I observed Surbhi to be diligent and conscientious in her work.
She encountered various issued during the experiments, and is willing to stick at a problem till it
is solved. She also has a cheerful personality and works well in a group.
Please do contact me should you require any further information.
Sincerely,
Arnab Bhattacharya
