Bubble Wrap

The older children showed Lincoln and Evan how to have a good time with bubble wrap. You have to be old enough to jump well and big enough to pop the bubbles. 

Lincoln recently acquired both of those attributes, so he joined his siblings in popping the bubble wrap. Evan was suitably impressed.

Jake took the fun a little too seriously. When he didn't pop every bubble by random jumping, he used his fist to finish the job. Ouch!
