2 coat hangers
4 to 6 corks
Join the two coat hangers together! This might take some finesse with the electrical tape but you can do it!
The hanger allows air to flow inside the wetsuit when it is hanging up - this way the wetsuit dries out and the bacteria that make it stinky die off. Other good practices include not peeing in your wetsuit and hanging the suit inside out.
You can buy a similar product (for about $30) and a version that includes a fan. I think this is way cooler.
