We did clap till our hands pained , we did whistle till our throats pained , But that day we were touched by god .

Only a very close group of people who hail from a particular engineering college knows this incident. 
We had organized a state level inter college tech fest . Among other things  we also had the science part of it . The only rule was to keep working  models there . Either innovated or copied from some place . in a nutshell anything moving with explanation of theory  behind it was eligible to be part of the expo.  We got over whelming response from  various college groups . and also had some pretty  impressive projects over there . . College  authorities got Sir APJ Abdul Kalam as guest of Honour . Before he came in to the expo , it was inspected by our and other college eminent  teachers . So there was this group , there project was to  turn ordinary toys to signal controlled . They had actually converted a ordinary cheap toy bus to clap controlled by very cheap investment.  However on the d day , their project didn't  operate as expected . The inspection group  asked them to not display a failed project and be a part of the volunteers there in hall. They  vacated the space. 
Then comes in Sir APJ .  He listens and observes every project . gives suggestions and comments , appreciates, suggest better ideas . He  even discusses the  source of idea etc. The  interaction with him was nothing less  than awesome and all the superlative words you  can think of.  When  he completely surveyed the hall , i.e.,  a good  2.5 hours , before leaving  he asks  why  is there a gap over there, and  points  to the good 2-3 feet abrupt vacant  place recently vacated  by the failed project group . 

Our Senior professor told that the place was held by a group whose project failed some how that morning. He apologized for the same to Sir APJ . After listening  , he calmly asked if it is possible to show him the demo of the failed project. The team was there in the hall as volunteers , they were immediately summoned to set  up and display , explain whatever they  had . In 5-8 mins that vacant space didn't exists. They spoke about their  demo . Sir APJ listened to them , and had a close look . He asked them what could be the possible cause of the device not  working . The nerd of the team said  , it  should be because of some IC gone  crazy , he asked them  if they would be able to  fix it . They said  yes , all they would  need is a Silver foil and a solder iron . We arranged that. it took  whole 30 mins to set  up. The teams project worked. He appreciated and left with the calm he came with . 

We did clap till our hands pained , we did whistle till our throats pained , But that day we were touched by god  .
