Hi, hopefully this is the correct place to post this question.

I'm using a bubble machine for an event indoors. The floor is just plain concrete and will become quite slippery when the bubbles burst over it.

I want to put down some kind of temporary floor over the top of it to stop it being so slippery. Does anyone have suggestions for a type of material? I was thinking that fake grass would be best but it doesn't fit the theme of the event. Does anyone have suggestions for any flooring materials to cover an approx 5 x 5 m area?

thanks
