A hand pours a bright red, viscous liquid into a clear, circular container. The container already holds several small, black plastic spiders and a single googly eye, partially submerged in the liquid. The container sits within a larger, clear rectangular tray on a dark grey surface. The red liquid appears thick and almost jelly-like, creating a visually striking contrast against the black spiders and clear containers. The scene suggests a Halloween-themed craft or sensory activity in progress.

A small, rectangular glass bottle stands on a white surface against a plain, off-white background. The bottle is sealed with a silver screw-top lid and contains two distinct layers of brightly coloured liquid; a layer of pale yellow sits atop a layer of a more vibrant blue. There is a very slight mixing of the two colours where they meet, creating a thin, slightly green band. The bottle is positioned centrally, and the image is sharply focused, highlighting the clear separation and bright colours of the liquids. The overall impression is one of a completed sensory bottle, ready for use.
