Man it's been ages since I've been on here. Things have really been changed up.
So yeah, I made this the other day for the fun of it. It's a working knex fan that has 4 blades that spin at roughly 555 RPM. Now I would say that's pretty good for a knex fan. It's small enough to fit on a desk, but strong enough for you to feel a breeze. So yeah, it's nothing that special, but I thought I would show it to you since I haven't been on here in like 4 months.
