Big sister erupts with disappointment over gender reveal volcano

The suspense is there, but the only thing to erupt from this gender reveal volcano is a big sister's disappointment.

The mum and dad in question had created a rainbow coloured volcano to share the news that would spew forth pink foam for a girl and blue foam for a boy.

The girl and her sister put spoonfuls of a powder (we assume it's bicarb of soda) into the playdough volcano, and pretty soon foam starting pouring out of the top.

"Ooh, here we go," exclaimed their excited dad. "What colour is it?"

"Blue," reply the two girls together dejectedly, clearly not thrilled with the outcome.

"Awww, I didn't want it to be blue," complained the older sister.

"You're getting a little brother," chirped their mum, trying to salvage the situation.

"Aw, I wanted pink!" shouted the girl. "Noooo, you made it the wrong colour!"

The parents saw the funny side and laughed off the girls' response. Hopefully they'll come around in time.
