Martin and Maya mixing vinegar, universal indicator, and amonia to see how the pH balance changes.My Brother and Mom and I all went to OMSI. In OMSI there was a ball room which showed aerodynamics. We got to watch The Mistery of the Nile in the iMax theater; it’s a theater surrounding you on the ceiling and the walls in front of you and behind you. It was scary! In the chemistry lab, I got to do experiments like making chemical reactions (vinegar and amonia and a universal indicator, which changed colors) and gel beads. And I learned my lesson to always wear goggles! Because I squished a gel bead and the inside squirted my lens.
