here's my favorite way to explain infinity to non-mathnerds
You own a hotel it has infinite rooms on Day 1, an infinite number of guests check in your hotel is full on Day 2, a second batch of an infinite number of guests check in ..you ask all the guests from day 1 to move up to their next even-numbered room ..the new guests check into the odd-numbered room everyone gets a room your hotel with infinite rooms and infinite guests is still full. repeat as neccessary.
granted, that's a purely integer example, but it's a nice way to answer kids who (like we all did) ask questions like 'whats infinity plus one?'
