Are you thinking about trying a STEM challenge with your kids?
What's inside? Well, initially I thought about having the kids design and construct a megaphone.
Thirty seconds later a voice in my head scolded me:
The best part of this challenge is that you can keep the best voice mufflers handy in case you are having one of those days where you just need to belt out something really loudly but know you can't. Just use the voice muffler and then go about your business as usual. Enjoy!
