Femi and the Mindfulness Machine

"Tomorrow is the science fair at school and Femi has built his very own wind machine. But there is a problem... it doesn't always work. This makes Femi feel anxious. What if the wind machine won't work on the day? What if his teacher doesn't like it? With Grandma's reassurance and special calming techniques, how will Femi and his wind machine do at the science fair?"--
