How do you make a homemade pregnancy test with house hold items?

haha actually I've read that you can use danelion leaves to find out if you preg. i guess you pull all the yellow leaves off, don't use the stem (just leaves and they have to be moist- not dried out). then i read you pee on the leaves, let them sit for like 10 mins to an hour and if red blisters appear then your pregnant. if it really works my guess is that the hcg in your pee reacts to whatever moisture is in a dandelion. weird, huh...
