Jello in a Jar

How cool is this? And you can eat it! Now I hate cooking and I don't really care for sweets but I have to admit that bright colored items in mason jars catch my eye.
This awesome idea is from the CookBook Queen

Another cool idea is this Rainbow Jello in a Mason Jar from Sugar and Dots.
This would taste so good on a summer day.
I would really like to make these and take one to work and eat it!
