The plastic bottle version of this activity is super user-friendly, but it also uses plastic. So, I tried to create a glass and fabric version. I used an old olive jar and a mesh shopping bag. I grew sprouts through the mesh shopping bag. This worked well (although I recommend trimming the fabric so that it will not wick away the water out of the jar!), but is more dangerous because of the glass. It is also more expensive and temperamental because of the fabric. However, I am confident that students can engineer some creative solutions!
