edit: Steve Mould's video "I Made a Lens, But for Sound" demonstrates how balloons filled with gasses of different density than the surrounding air, act as a lens on sound waves. Helium filled balloons will scatter sound because the helium is less dense than air. He shows how a balloon filled with carbon dioxide can focus the sound.
- 2007(7th): The mosquito ring tone was a popular notification ring tone. I recall a friend testing it with my math teacher during class. He could not hear it.
- 2010(10th): The last time I recall passing notes in class... I got caught. Apologies to my Geometry teacher. He was one of the best teachers I had.
- 2012(12th): I(late to the party) bought my first phone... The only time I recalll using my phone was when went to the bathroom and accidently dropped it in in the toilet. :'( ... 3 days in a bag of rice and it worked just fine. I'm sure I must have used it in the toilet too many times for that to have happened, but I don't recall ever using it in class, as the punishment was confiscation of the phone and it wouldn't be returned until a parent signed off in person.
Considering this with the recent price increase, and some trouble with my family plan, my initial reaction was quite negative towards YouTube. They are setting a very clear trend against what I want in their service with recent changes (Removing downvote, removing android shortcuts and other features, aggressive copyright stiking policies, aggressive promotion of shorts, terrible recommendations).
I am considering cancelling. However, a more optimistic view would be that their ad block policy could result in lower subscription fees with more ad and subscription revenue.
