electrocuted iPad

So rather than me being electrocuted, my iPad was.

iPad 3rd generation, 32GB, Verizon LTE edition. I bought one of those electric bug swatters (pictured here http://www.pplmotorhomes.com/parts/recliners-chairs/14-9413.htm)

It's a $2.00 device and it says it can electrocute bugs with 1600 volts. Sure it has successfully killed bugs, I have touched it and I didn't experience anything but a slight pain. Anyways, my iPad came in contact with it (don't even bother asking how 😝 ) and the screen started to change colors then stopped once the swatter turned off. The iPad is functioning fine and nothing is wrong but I am still worried. Anything I should check or do.
