Just drink hot water. But extremly hot water about 5 8oz cups should do it. Then sleep with 7 blankets on. You will have a fever but if you don't, eat a lot and then make yourself throw up twice. This works all the time. I have missed 21 excused days from school due to this.
There are a lot of ways to get a fever, but there is one that always worked for me. Hold a raw onion under your arm pit for 30 mins. (Half an hour). You will see how your body temperature increases.
Put onions under your armpit and I tried putting onions in my socks. Seriously, I got a high fever. Really works, then I ate sweets and didn't drink, then I stayed up all night. Seriously 100% works.
I did this once, because I needed to miss my date. I took a shower and turned on the water really hot, then in the shower I ate some shampoo. When I was done, I put on a pair of sweat pants and three sweaters and drunk ginger tea. I puked for two hours. I missed school for like three days.
Vomiting gets you hot because of the pressure you use to get the chunks up. To vomit, crack an egg in a glass of orange juice then stir it up really well and drink it. You will get a fever and you just threw up, so no school or work for you!
Buy chili pepper and eat 1/4th of the teaspoon. I tried that in school, then I got really high fever, then I was sweating, and the nurse let me home! But then, at night, you'll have to experience sore throat and a gassy stomach because of the pepper. But it still works.
Just eat chocolates, don't drink water, next, eat fried chicken. After a while, you'll feel that your throat is very dry, resist drinking water, and slowly you'll have a flu & a sore throat. The next two days, if you still have a flu & sore throat, you'll have a fever.
I just got a "fever" by taking a shower and getting a bunk of water in my nose. After that, I held a super-hot rag to my forehead. My mom thought I had a fever, but she gave me the thermometer anyway. I ran upstairs and said I wanted softer tissues to blow my nose, after that I got my water in my sink hot and put the thermometer in it. She bought it, so now I am staying home.
I heard that the big red gum gets you a fever by chewing it for a couple of seconds and putting it on the back of your neck. My friend's tried it and said it worked. I just bought the gum yesterday (Saturday) and I'm going to try it tomorrow morning; I hope it works.
Well, last time I got a fever by eating a whole bar of chocolate but not stopping - only keep eating until there's none. I never knew that eating a whole bar of chocolate would make me sick and I found myself terribly dizzy in the morning one day, near fainting.
The one thing that gives you a high fever is an infection somewhere in your body. Also an injury somewhere that has gotten infected. Flu and cold symptoms will cause an increase as well.
Take a bike, go as fast as you can, without dropping dead.
Do that for at least fifteen minutes. Never sit down on the saddle, because then you're not going fast enough.
You'll be corpse white, around 40°c fever, fast heartbeat, and sweat for about one hour.
(You might also want to refrain from eating that day. However watch it you might pass out using this.)
Eat at the Golden Corral. They have so much food your stomach will hurt. Then tell your parents you feel sick. Or fake it. I feel sick and the next day I'm fine but I act like I'm still sick.
