Solve four riddles in one short video (2min 21sec)

[lindamaxwell]

There are four riddles in this short movie. It's pretty neat! The answers are actually subtly given, but if you're just watching the movie, you may not catch the clue; especially the fourth/final one. If you want to solve the riddles before the answer is subtly posted, here are the spoiler marks so you can pause before it's shown:

2. Rearrange these seven letters to create a new seven letter word, ASSUAGE. Answer: ~46sec
3. This one asks you to rearrange six matchsticks so that all six touch. There is a mistake in the answer given, so you can solve for both the answer, and also find the teeny tiny "mistake" in the answer that is shown/given. Answer: ~1min 20sec
4. Solve this puzzle: HhAaNnDd. Answer: ~1:57 sec
