Science: They continued there work in chemistry by "exploding" plastic canisters using alka seltzer. Then they transitioned to the material sciences and made slime.
The big adventure of the day though happened later. After la comida we took all the teen leaders, gringos and locals, into la capital to go roller skating. The kids were super excited. Then, after a very loud hour bus ride (I am now officially burnt out on "despacito") we arrived at Rollers to find out that there was a skating lesson taking place and it was closed to the public until 5. Well, as my loyal followers should know by now, one must always have a plan B here. Which we fortunately did. We got back on the bus and went to a mall not to far away for pizza and a movie. But not just a regular movie. We saw the new Transformers movie in 4D! This meant that while we were wearing our 3D glasses the seats moved with the action and they sprayed us with air or water as the plot indicated. In general I find all that more distracting than entertaining (I can barely handle 2D after all) but the kids had a blast. And, since the movie was really bad ( if they're going to make a summer blockbuster technology filled movie the least they could do is have the plot make sense and write some good dialogue. Is that too much to ask?) all the 4D antics provided much needed distractions.
On a side note, at Rollers the students in the class were all decked out in traditional figure skating outfits complete with flesh colored tights that went over their skates even though the didn't really match the actual color of their flesh. And they were practicing axles, flips and toe loops(that's right I know some figure skating terminology. What of it?) The question I have is what exactly they were training for?
