The static shock is caused by an electrical charge built up in a person, changing them from being neutral to being negatively or positively charged.
Once charged, if a person then touches something that is conducive to electricity, it causes a static shock.
The cause is usually dry air and the materials that rub against each other.
It's not uncommon for people to experience static shock when jumping on your Vuly trampoline.
The material of the trampoline surface is usually the culprit. If the surface is made of nylon, it's a good conductor for electricity and can cause a static shock.
Note: Synthetic soles are usually the worst sole to wear to reduce static shock, as they are a great conductor of electricity.
We hope you've taken away some tips to reduce those nasty static shocks.
