WATCH: Prague zoo animals combat heat with ice-cream

PRAGUE, Czech Republic— Zoo keepers feed gorillas and polar bears at Prague zoo ice lollies to help them combat record temperatures during the heat wave sweeping across Europe.

"We take a bucket, either 12 or 15 litres, we chop about two kilos mostly of fruit but we also add vegetables, then we take a two-metre rope with a knot at the end, we put that on the bottom of the bucket, add the fruit, pour water over it, put it in a freezer and the next day we have ice-cream,"  Vit Lukas, primates curator said.
