Wengie: So, this next hack says, that you can seal these card envelope things with toothpaste, instead of licking it, yeah, this might be useful for like germaphobe, but, don't want to lick their envelopes, or, if your envelopes happens to be super dirty, and, you don't know it's been, so, let's give it a go, yes, I'm gonna take a super small amount because we don't want too much come on up close, I took a small amount of toothpaste, and just applied it to the sticky part, and, hello, okay, it didn't work, so, I tried using more toothpaste, and, managed to actually stick it down, but then, I realised it wasn't very secure, and, I could easily open it again, it doesn't feel very strong, the seal, pretty easy to open guys, how'd, it didn't work out really well, I'm sure it's good for like those sides you want to seal, but not really seal, but, if you actually want to close up an envelope, this ain't gonna work, just use some water ion your fingers, put it on the glue, I think what happened was toothpaste created a barrier between the paper, and the actual glue, and, that's why it isn't sticking very well, so I think this has worked for you guys, tell us down below because I can't see it working for anyone, so, I'm gonna give this hack a thumbs down!
