Hey folks, Week 3 is already over. Time sure is flying. It’s important to find things to do and to stay busy with experiments. Make sure every day is a good one. Here’s some cool pictures to make sure you have a good day. On the left is a model of a shallow well pump, which looks like a strange blue submarine to me. On the right is a sieve full of 2mm zirconium silicate beads, in the shape of a smiley face 🙂
