I did the salt ad ice challenge like two weeks ago and it got swollen and red . But now the skin has came off one scab ( both on the same hand ) And I can see ( I think it's my meat ) ! I don't want my mom to find out and I don't kow what to do AT ALL ! Helppp ?

That is like a third degree burn and you should have gone to the hospital to have to treated, you still should if you cab see the flesh underneath. You should show it to your mom, this is a serious wound.

I also did the salt and ice challenge yesterday and it looks like I burned my hand with an iron! And also, I have little scratches there. Should I be concirned? Also, mom doesn't know.

Yes, you should be concerned. This is a very stupid thing kids are doing these days and it can cause serious infection if not treated properly. Show your mom and get medical attention.

But I washed it right away and I showed it to my mom, she put something on it to heal... looks like it's getting better... but if it doesn't look better tomorrow, I'll go see a doctor.

I just did it and it's purple and is bumpy...

Congratulations you have a burn. Go to your local medical clinic and get it looked at. Keep it covered and clean at the very least.

Also, you failed the intelligence test that was inherent in this challenge. To pass said intelligence test you have to have NOT done it. For your homework you will figure out why this burned you. As well as reflect upon the fact that you will have this scar for the rest of your life reminding you what you did.
