How can you make yourself throw up?

so i just ate a small pack of skittles and after i relized that there was a hole in the pack and im like paroniod about something being in it now. and i jjst dont feel good at all. i tried stinking my finger and toothbrush down my throat and i almost got it but i just end up gagging and coughing. i tried chugging soda and water it didnt help. so that wont work and i dont have access to that syrup stuff that makes you throw up a lot its like ipeaec or something. so something else that i can make at home and does drinking salt water really give you the runs???
