we'd like to see it. >> can you see it there? >> yeah, go for it. >> so yeah, you can see inside the salad spinner there's a yogurt container that's propping up cones. and in between the teeth of cones we just set these tiny little test tubes that contain the blood samples. so we spin it for about ten minutes just using the pump-on top. and afterwards it will separate between the plasma and blood cells. >> the pump-on top, it works that way. you didn't really have to overhaul it much or reconfigure it to work? >> no, all the salad spinners own mechanism. we don't have the engineering background to completely revamp the salad spinner. >> you're going to take one later this month, i'm hearing? are you excited about that? >> yes. we've been testing it in the lab all semester so it will be nice to demonstrate in ecuador. we're not actually able to test it but we will be get feedback
