I agree,Arushi, I never would have thought that one day people would advertise by putting their logos up in the clouds! It's like "Wow!Look in the sky! It's a bird! It's a plane! It's...an apple logo...?"

I agree, it is a really great invention! But, how are they making a profit from this? Also, how do they know someone isn't just getting free icecream over and over again by smiling repeatedly?
