纖弱

纤 = 千 + 纟 : Marie Curie (xi) finds that there are many fine (纤) silk worms (纟) in front of the anthill (a1). She wants to preserve the delicate (纤) worms and thus puts a kilo (千) on them to press and dry them.

弱 = 冫 + 弓 : Rachel Rhinoceros (ru) created a piece of art in the observatory's bathroom (o4). She joined many composite bows (弓) by sticking their ends into popsicles (冫) which weren frozen again afterwards. Her whole construction is a huge armchair, but it is very fragile and weak (弱), so Rachel puts on it many of these "handle with care" stickers.
