We put some iced water in some bowls. Then we made two sets of gloves. One was just one plastic bag. The other was made from two plastic bags with lard between the bags.
Next we put our hand in the single bag and put it in the bowl of iced water.
"It's freezing," said Ethan.
Then we put our hand in the bag with the lard. "It's warm," said Ethan.
Himanot tried the same.....
"It is still warm," said Himanot.
We thought that the water might have warmed up so we tried with just the single plastic bag again. It was still freezing.
