No longer will you have to create your own spit balls and waste your own precious resources. You can purchase these polymer spit balls that will actually grow 200x their size. They’ll slip, slide and will only explode once they’ve hit their target. I’d like to say that only the kids would find this interesting, but we all know that we still get a thrill out of those juvenile activities we did as a kid. You can purchase a pack of these for $4.95.
