On Friday I went with Francesca, Cheyenne, Theresa, and Nick to Lake Calhoun. It was pretty cool at the beaches and the water, from what I was told, was cold (I decided not to go into the water). After we were done at the lakes we went to see the fireworks near Saint Anthony Falls Laboratory. It was the coolest fireworks show that I have ever seen. It was really cool because we were extremely close to where the fireworks were being shot off at. The rest of the weekend I did not do much and today Francesca and I took all of the sand and pebbles out of the column to determine, more exactly, how much salt was left in the column.
