Wife: So what did you and the kids do today?
Husband: Nothing much, just a little walking on water.
Wife: Walking on water? That sounds dangerous.
Husband: Yeah, we almost lost little Timmy.
Wife: This is the last time I let you take the kids out without me.
Watch these people run, jump and bike on 8,000 litres of non-newtonian fluid in Kuala Lumpur, Malaysia! Pretty cool.
