Digital Survival Kit Idea

This is a re-post of one I put up about 3 or so years ago.  It's a suggestion for a Digital Survival Kit, designed by a teacher in the US for his class .. mainly to reinforce some of what he teaches.  Sometimes visual props can make a point better than all the words can.  
Any other suggestions to add?

Padlock: to remind you to have strong passwords
Toothbrush:  Would you share your toothbrush?  No? Don't share your passwords either.
Permanent Marker:  EVERYTHING you put on the Internet is there forever
Toothpaste:  You can't get toothpaste back into the tube - nor can you ever take your posts off the Web.
Magnifying Glass:  What shows up when people search you on Google? Is that what you want people to know about you?  Will it get you a job later?
Fake Tattoo:  'Digital Tattoo' instead of 'Digital Footprint'.  Footprints can be washed away - a tattoo is much harder to get rid of.
Sheet of paper:  Screw it up, stomp on it - now smooth it out and try to make it as new as it was.That's what happens with cyber bullying - the marks are always there.
Strainer:  Know how to 'strain the real' from the Internet.  In other words, know how to spot fake stuff and don't get caught out by hoaxes.

Digital Citizenship Survival Kit

Always being one for visual props and ideas, I came across a Digital Citizenship Survival Kit for students.  This has been designed by a teacher in the USA for his digital citizenship classes, to hand out to his students, mainly to reinforce some of what he teaches.  
What do you think?  Any other suggestions?

Padlock: to remind you to have strong passwords
Toothbrush:  Would you share your toothbrush?  No? Don't share your passwords either.
Permanent Marker:  EVERYTHING you put on the Internet is there forever
Toothpaste:  You can't get toothpaste back into the tube - nor can you ever take your posts off the Web.

Below is a link to paste in that is a quiz about Digital Citizenship.  It could be interesting to try it out on your class.
