Could I get In Trouble For Doing This?

No. You can't get in trouble.

Okay, it really depends on your definition of "trouble." Yes, the cops (or homeowners) can harass you a little, tell your parents, and even press charges. However, you're not going to go to jail or be fined or anything like that. Egging and stringing does constitute vandalism, and probably one or two other offenses depending on your jurisdiction, but if you didn't help you aren't guilty of anything in the legal sense.

You should know, however, that if you did so much as purchase or carry any of these weapons of destruction you have aided and abetted, and you can be punished to the same extent as your friend. Solicitation can also be an issue for you if this was your idea. If you said anything like "Hey, you should go egg John's house" to your friend you have solicited him to commit a crime and can be punished.

Edit:

If you didn't buy them or even touch them, and it wasn't your idea, you're good to go. Like I said though, they can still harass you a little. Nothing to worry about though, legally speaking.

You fit the definition of an accomplice. By not reporting or attempting to stop the crime you are guilty even if you did not destroy any property yourself.

A prank is a prank don't worry about it.

Sounds like a good time, and yes you can get in trouble. nothing serious though

Guilty by association.
