the gas from the Bunsen burner will cause the existing flame to flare and burn the entire piece of paper and your fingers - and the lab. it's difficult to blow out the burning paper.
The moving air under the paper reduces the air pressure. Since the air pressure above the paper is unchanged, it pushes down on the paper. The shape of an airplane wing forces the air passing over the top to move faster than the air beneath the wing. The difference in air pressure causes the wing to lift.
Tissue paper is not very dense. I assume it is one piece and is on a flat surface. When blowing down straight and in the middle, air is able to move through the tissue paper because it is porous. You keep forcing air down and the molecules are bombarding each other and when completely through the tissue paper the fastest way to escape and allow the other molecules through is by escaping under the tissue paper and outwards. This is what lifts the tissue paper.

When you blow - you're moving the air that was static over the top of the paper. This lowers the air pressure relative to the air underneath, so it pushes upwards on the piece of paper.
First you rip a small piece off of some paper product (napkin, computer paper, etc.). Then you wet it with spit and stick it in the end of a straw. Aim and blow!
tell them to blow their nose REALLY hard.

When you blow on the glass, your breathe condenses and provides a small amount of fairly hot water on the lens which helps clean it.
Pull back your tongue I think.
Check the door seal u can do this by hanging a piece of paper from inside and running a blow dryer around the outside of door and see if the paper moves.

The hidden map piece is in the yellow tooth of the big skull rock.You have to push the box of dynamite all the way down so that it's in the water and then push it under the yellow tooth. Then go over to the cannon on the left of the yellow tooth and click on it. It will fire and hit the dynamite which will blow up the yellow tooth. Then you will see the hidden map piece. Jump up and get it.
