1) A fake highlighter that is actually a casing for a pipe (so that you can smoke pot or whatever other drug of choice). These are available on-line or at specialty smoke shops. Most parents or teachers would assume that a highlighter would be okay to find in your kids backpack or room. But highlighters are not really safe anymore.
2) Fake water bottle that houses drugs inside. To the average person it looks like a normal, full water bottle. The top section is filled with water as is the bottom section. But the top section pulls out to reveal a hidden chamber for hiding drugs. People sneak drugs into school, concerts, sporting events, etc. with these tricky bottles. Also easily available to kids and they cost around $20.00.
Do you see what we are up against? The conspiring men of the world are getting sneakier by the minute.
I will post later with my notes (and statistics) from the event.
