How to save cantaloupe seeds

Here's how I get my own cheap seed from cantaloupe we buy at the grocery store.Seeing I can't do any outdoor gardening I decided to do some experimenting with these seeds I saved.This is part one of three..will post the second and third part (germinating and planting) shortly

 This is the piece of cantaloupe I'm taking the seeds from

 Here I have the seeds and some pieces of fruit..next step they must be cleaned

 The seeds have been cleaned through a strainer

 Here I'm testing them to see which ones will sink and which ones will float

 I skimmed off the ones that floated 

 Here are my finished seeds..I'll let them dry before storing
