Surely this one is straight out of the movies or some superhero comic book? You would certainly think so, but this highly effective spray can turn opaque paper temporarily translucent, allowing you to view the contents of an envelope without ever actually opening it. Thirty seconds later, the envelope will return to it’s original state, leaving no marks, discoloring or indeed any other indications that it may have been tampered with (left image)
Another spray - Clue spray - is designed to leave an invisible film on any surface, which when touched, is transferred to a person’s hand or clothing. Looking for clues or a suspect? Then look no further. Unknown to the victim, the spray remains for up to five days, even if the hands, for example, are washed repeatedly. The spray can’t be seen by the naked eye, but shows up as fluorescent under ultra-violet light (right image)
This is isn’t the first spy camera I’ve come across that’s placed inside a belt buckle, but this is definitely the most classy way to pull it off. Nothing says elegant like a Playboy Bunny belt buckle. Then to give it a whole new level of chic, you throw in a spy camera right at waist height. With this belt you’ll be ready to go for your next night of expensive strippers and keep up your reputation as the local peeping tom.
- A week before the exam review everything of the examinations scope in your subject matter.
- What ever reading technique you prefer to use as if you are comfortable. (I use the rewriting method)
- Then a day before the exam, enjoy, eat, and relax and the most important is to sleep well. Let your mind have rest and avoid stress.
- At the time of examination, do not waste time for questions which you cannot answer and note the number you will leave blank, rather proceed to the questions that are easy.
- After answering the easy questions, then you may go back and answer the items you've leaved.
