Spotted Reputation
There is a great idea how to play a trick on your colleagues and friends. Mix liquid ammonia and phenolphthalein (you can buy it in the drugstore). Finally you will get a reddish rose liquid. Pour it into a fountain pen. When you have the chance, shake off "ink" to your colleagues' white blouses and shirts as it were accidentally. Red spots on their white blouses and shirts will provoke storm of their indignations. In a second liquid ammonia will evaporate and spots will disappear.

Squash Paste
To play a joke on your friends on April Fool's Day, you will need to buy or cook squash paste. Put squash paste on stairs in his or her gate. You can "decorate" it with toilet paper to have an effect. When you go down stairs with your friends, they will be shocked and pass around the "heap" very carefully. You should come to the heap and say: "Oh, it is fresh!" and start to eat squash paste. You will have a fabulous effect!!!!!

Have a great time on April Fool's
