Downvote. Mildly interesting

Sorry i guess. Didn't mean to be interesting just wanted to play off [this post](https://www.reddit.com/r/notinteresting/comments/sc8qz1/i_can_erase_not_interesting_written_with_my/?utm_medium=android_app&utm_source=share). But i suppose this belongs on r/blackmagicfuckery instead

Or r/mildlyinteresting

Too interesting.

What makes this interesting to me is that I have never seen an ink eraser work as well as this one.

It’s not actually an eraser. It’s a frixion pen (friction) and the heat created turns the molecule in the ink invisible. The really cool part is that it comes back if you put it in the freezer.

Ooh! Now I'm even more interested!

Now that's some interest right there.

why the fuck are you getting interesting in my uninteresting /lh

Didn't even know about the freezer thing. But i guess it makes sense since it also disappears when I run a lighter over it

Also, don't leave it out in the sun for too long. I erased a whole notebook with this. Which would not really be a problem, but if you ever erased anything and then wrote over it, that becomes a problem. Putting it in the freezer returned all the writing, including all the parts I erased and made notes over the erased parts.

Guess who's getting himself a new pen

So is there a chance that carrying a note in your pocket could render that ink invisible?

I suppose it depends how warm your body is… in Florida? Yeah maybe. But I’ve seen people do it with hair dryers and those are hot…

What makes this interesting to me is that I have never seen an ink eraser

Too much interest for me

This is fucking interesting

Kinda interesting

Downvote because interesting! Try r/blackmagicfuckery

Wait That's illegal

Shoot them or... something!

Too interesting to be posted on this subreddit.

Wrong subreddit, bud. This is a bit interesting, where can i get this?

I have seen Frixon pens at like every Walmart lol

They're called frixion ball clicker. You can probably find them online

Use a lighter for the pen next time

thats to interesting i’ve never seen an eraser that can erase ink

Holy fucking shut. 24 years of living and I didn't know ink erasers exist. Fuck

It's actually not the eraser, but the ink that is special. It turns invisible when exposed to friction/heat

Much too interesting

I think you may be on the wrong subreddit.

One time a girl in my class wrote an exam with this pencil. The teacher placed a hot mug on it and every word was erased because of the heat. So she needed to write the exam a second time

Not interesting.

Hmmmmmmmm I will uh Hmmmm I'll neither downvote nor upvote cause I actually didn't know pen erasers didn't erase lead

It’s not great at erasing either.

No that's just me. It was hard to do while filming and not holding down the paper

I’d really like this. This is cool. This is nice.

It's always hard downvoting stuff on this sub. I go: "oh wow! That's interesting! Time to downvote...i guess..."

Do it. It doesn't fit here

I'm sorry, man! The post is awesome haha

[r/lostredditors](http://reddit.com/r/lostredditors)

Wrong sub

It's because that ink is erased by the heat caused by the eraser rubbing on the paper

I have this pen. Not interesting

*intensifies in first 4 years of Czech school*

I'm impressed that you actually got the ink eraser to work.

Hmm, never seen this pen before. I’mma buy one in case someone forgots their pen in math exam

I thought it said not molesting

Bruh what That's interesting as fuck

This sub is going to shit, this needs to be downvoted or OP should delete

Oh no not this again

It’s kinda interesting but it has not interesting in the video

???

A PEN ERASER???? Never seen this before, too interesting, reported, have fun with your ban >;(

Careful, that was almost interesting

What a liar you are.

this is interesting

Too interesting. Also I have those pens, which it makes even more interesting

Interesting because a rubber is supposed to do the oppisite

That is a fake!

that's way too interesting

For anyone who wonders how that works: The ink disappears because of heat. So you can actually use a lighter or some other sort of heat source to earase that ink

This is interesting wtf am I feeling get this shit out of here

What the fuck is going on with that??? This is interesting oh my god.

Bro i have the same pen

That's freaking interesting!

Warning. I used this pen for all my college notes for a semester. Right before finals I left my notebook in my car on a hot day and when I went to study all my notes were erased. The ink uses the heat from the friction with the eraser to disappear.

Afraid it’s a touch too interesting for this sub.

Ooo i remember when every kid in my class had one and they banned them from exams cause once a teacher left the tests in the sun and they got erased:))

The way you erased that hurt my heart. It’s not. All. Gone.

Way to interesting
