Recently we purchased an Arduino Uno R3 Microcomputer Kit to add to our Makers Lab. Below are some highlights of the boys with their dad coding and experimenting with the computer.

Update! Analyzing A Chicken Bone
So what happened? The bone that was in the water container smelled awful, retained its color and was still hard. The one in the vinegar container was odorless and the bone was softer. What is so special about vinegar that it can make a hard bone soft? Vinegar is considered a mild acid, but it is strong enough to dissolve away the calcium in the bone. Once the calcium is dissolved, there is nothing to keep the bone hard - all that is left is the soft bone tissue. That is why it is very important to include calcium in your diet.
