In this instructable, I will cover ways to write secret messages using tape. I will also cover a couple of ways to use tape that are unusual.
Note: most of these are meant for being funny. Please don't just rate with 0.5 stars because these wouldn't work in real life. If you are looking for a real method of writing a secret message with tape, see step three.
Step 1: Secret Method #1
By far the simplest method of concealing a secret message using tape.
Write your message on the protruding part. When the person reads it, they simply detach the tape.
Step 2: Secret Method #2
Write your message on the side of the tape roll. Given enough time, the tape will be used and the message will vanish.
Step 3: Secret Method #3
This is the least silly method and the most real one, too.
Take a piece of tape and put it on the table (it must be a dark, flat surface). Secure both ends, but not the middle. Picture two shows a good example.
Take a somewhat pointy object (not sharp, not something that will make a mark) and "write" your secret message on the tape with it.
When the tape is peeled up, the message (almost) vanishes!
Step 4: Other Strange Methods
Method 4: Write on a Rubik's cube. mix it up. Put a piece of tape on it. If the saboteur doesn't know the secret of the tape, he can't solve it!
Method 5: See picture 2. The watch face is unreadable!
Method 6: Cover the earbud with tape and play the secret message through. If the person doesn't know about the tape, she can't hear the message.
Method 7: Cover the spy's eye with tape. [pics 4+5] He can't see with that eye!
Step 5: Other Uses
Put it on someone's nose to confuse them!
