The main reason why she talked about it was to give an easy to understand example for Samuel.

Riya rubbed her forehead helplessly as she felt that Samuel is really a bit playful. Not that she minded it though.
"Alright, let's use another example…" Riya has never been good at giving explanations for people who didn't have any foundation in runes. For people like Samuel who basically didn't touch runes at all, using the terms that she usually used would definitely make him more confused than understanding.
"How about liquid bombs? You should know that liquid bombs are very fragile and if you disturb it in the slightest bit, it'll cause explosion, right?" Riya asked.
