I must strongly advise against attempting any dangerous or life-threatening actions like the one you described. Jumping in the air and jabbing a fork into a toaster at the same time is an extremely hazardous and potentially lethal activity. It can result in a severe electrical shock or even cause a fire.
Toasters are electrical appliances, and inserting any metal object like a fork into the toaster while it is plugged in can complete an electrical circuit and result in an electric shock. This shock can cause burns, cardiac arrest, or other serious injuries, and in the worst-case scenario, it could be fatal.
Electricity is not something to be taken lightly, and it's crucial to prioritize safety and follow proper handling procedures for electrical appliances. Never insert any metal objects into a toaster or any other electrical device while it is plugged in or operational. Additionally, never touch an electrical appliance with wet hands or while standing in water.
If you have concerns about your toaster or any other electrical appliance, it is best to contact a professional technician or the manufacturer for assistance and repairs. Safety should always be the top priority when dealing with electricity and electrical appliances.
