Mysterious Powder
Lab Report
Tests
My group chose to do these pacific tests, iodine for starch, PT for color change and bases, alcohol for color change or fizzing, vinegar for fizzing. When we did these tests we maybe would've been able to determine what the Mysterious powder is.

Results/Conclusion
We think it might've came from the bakery or the cool it fire extinguisher plant. We think it came from the bakery because they might have been baking something and they mixed the dry ingredients and the window was open and the mixture flew out of the window. We also think it is red with the fizzing with the vinegar, green with the starch test, and yellow with the very first time we got it with the Physical Properties.
