Fake a Fever Without a Thermometer

Do you want to fake a fever but have no thermometer? Well this Wikihow will tell you just how to do it!

Steps

Moan that you don't feel well, say you have a headache/stomachache and then say you're going for a little lie down. On the way to your room or sitting room get an electric heater pack and make sure it works. When you're alone put the heater pad on your head and leave it there for about ten minutes and then go to your parents and moan again, say you feel really sick and shivery. They should then feel your forehead and then think that you are burning up and let you miss whatever you were trying to avoid.
When you get up say you don't feel great but maybe some breakfast would help and go to the kitchen. Make yourself some toast/pancakes/toasted waffles and then press whatever it is against your forehead and cheeks for a couple of minutes. When your parents come down say that you keep having hot flushes and they will probably lay their hand on your forehead and find that you are very hot. Success!
Say to your parents that you have a bad headache and are going to lie down in your room, whilst in your room use your laptop for a couple of hours and then hold the adapter (black cuboid in the middle of the wire) onto your forehead and cheeks. Then go back to your parents and say you still have a really bad headache and that you keep having hot flushes, it is likely that they will feel your forehead and exclaim "Oh my! You're ever so hot! You must have a fever!" Done!

A mouthful of a warm drink can trick a thermometer into thinking you have a high temperature and vice versa for a low temperature.
If you want to use any of these suggestions but your parents have a thermometer, hide it!
Ringed out hot flannels work well too and you could stay under your duvet or rub your forehead and cheeks. Doing a lot of exercise before you get your parents to feel your forehead will also increase your temperature.
Depending on what your parents are like, simply saying "I don't feel good" and having a natural body temperature of {{safesubst:#invoke:convert|convert}} will do the trick.
If you really want to stay home sick, whether its for a test you didn't study for or you are just really lazy, set a quiet alarm clock for about 4:00 am. Go to the bathroom and dump a bowl of water in the toilet. Flush, go into your parents room and say you threw up. At the time you're supposed go to school your parents should call the school and say you're sick. Now keep up the act. "Sleep" in your room, play on your tablet or something - just don't get caught!
If possible, take some food from your fridge, chew it up, and then spit it into your toilet bowl. This will make it look as though you have thrown up the previous night' dinner or your breakfast, and your parents will believe 100%.

Make sure you don't make your fever TOO high, or they may take you to the doctors for something you don't have.
Don't get caught, nobody will believe you when you really do have a fever!
