10 a.m.-4 p.m. Museum of Discovery. $8-$10, free for members.
This sounds very cool, especially for those with young'uns (or young-at-heart'uns): The 2nd Annual Tinkerfest.
Organized by the Arkansas Discovery Network (a six-museum partnership with the Museum of Discovery as its hub), Tinkerfest will see more than 40 stations set up where burgeoning engineers and inventors can, well, tinker on stuff. What sort of stuff?
According to the MOD, "visitors will have the opportunity to create with 3D printers, disassemble a vehicle, meet robot makers, participate in water balloon catapulting duels, build and launch rockets, learn to crochet, create a cardboard city and much more."
It doesn't cost extra to attend Tinkerfest, but standard admission applies for non-members ($10 for adults, $8 for children).
