Invent a new beverage and name it.
A smooth fizzy drink that tickles your insides. It activates only when it reaches the tummy and then the giggles and laughter start. Mind you, it only lasts a few seconds per mouthful but it’s still great fun.
PS: Multicoloured bubbles float out your mouth if you burp after drinking. They tickle too.
