Amazingly, although Jon's team and our team took different routes to the Zoo, we both arrived there at the same time. We hunted around in the trees, and found a large bag containing several Ziploc bags with test-tubes of chemicals, and another bag of small strips of Litmus paper. Its contents:
Bag 1 had the number 11 written Each contained a vial of chemical.
Bag 2 had the number 10001 written
Bag 3 had the number 102 written
Bag 4 had the number 11001 written
Bag 5 had the number 101 written
Bag 6 had the number 122 written
We also found this sheet of paper:
We were a bit intimidated by this clue, as was Jon's team, so we pulled into the Shell station to work on it together. Of course, you'd have to be there to test the litmus strips, so here's the results of that test:
Bag 1 - Litmus paper turned red
Bag 2 - Litmus paper turned blue
Bag 3 - Litmus paper turned red
Bag 4 - Litmus paper turned blue
Bag 5 - Litmus paper turned blue
Bag 6 - Litmus paper turned red
Ammonia sure does smell good, eh?
