Lava lamp glass + water refraction (beginner question)

Noob looking for advice/tutorials on getting some realistic light refractions through glass and water for this lava lamp. I’ve messed around with it for a while but stacking the blobs, glass and liquid layers is throwing me for a bunch of reasons. Eevee is preferred as the rest of the scene will be in that but any knowledge is good knowledge.

Cheers

Oh just to note, I’m aware of / have been playing with SSR so those options are on for the scene and materials, but it’s probably not worth outlining my material attempts so far as they’re a bit rubbish

Take a look in this thread - some links that may help. Most of this refers to Cycles though.

This is perfect, I wasn’t sure where to start digging. Thanks for your help
