While it might be a no-mess eating scenario, I'm pretty sure I would make a mess getting that peanut butter into the bottom of the jar. But it does look like a good way to use the last of the peanut butter.
Here's a link to Nike's original blog post with more less-mess snack ideas: Thrive: Summer Road Trip #1: Car Snacks.
Honestly, though, I think these are too much work for me. But maybe that's because I have older kids. But I'm interested in hearing if you use any of Nike's ideas and how it worked for you.
Do you have any snack hacks?
