Terrariums

I went to Ikea and got three different glass containers, they were all of different shapes and sizes. I also got some tiny plants and made three terrariums on the Sunday afternoon.

This long glass container is ideal for making a terrarium. However, the glass surface fogs, I meant when condensation takes place, water droplets gathered on the glass surface making the contents not very visible.

This is a bit small and similarly, the surface fogs.

This container turns out the best. Unlike the above two, it doesn't fog and it was a beautiful terrarium.

Can anyone tell me why the above two fogs and this doesn't?

Hmm... what seems to be the reason?

This was the mess I created.
