ChemisTRY assembly



He did a really cool experiment where he mixed two liquids together and counted to five, for five different beakers.  Then they started turning colors every 5 seconds, at exactly the same rate he mixed the liquids.

He blew the cork off a bottle with hydogen peroxide in it.   We learned that fuel needed oxygen to help it burn.

He mixed two liquids together and when he swirled it it turned one color and if you shook it hard it would turn another color.

He poured liquid nitrogen over a balloon and made it so cold that it shrank up.

He used red cabbage to decide if a liquid was an acid or base.  If it's an acid it turns pink and if it's a base it will turn blue.

He said that diapers contain a powder that when it gets wet will soak up the wetness and turn to a gel.

He had 3 balloons filled with gas which he put a spark near.  One was helium which just burst.  One was hydrogen which caused a small explosion of fire.  The third was filled with hydrogen and oxygen.  We had to cover our ears when he put a spark near the balloon.  The explosion was SO LOUD!!  It was really cool.
