icicle

"My heart felt as cold as an icicle when I heard the sad news"

"How long do you think that icicle will hang from the roof before it falls?"

"Be careful not to stand directly under the icicle; it could drop at any moment"

"The icicle was so big it looked like a sword made of ice"

"After the snowstorm, we saw a huge icicle hanging from the gutter"
