Tangling spider, on drugs

My blog friend, Christine, sent me an article about a scientific experiment where they gave different drugs to spiders to see how it affected their webs. How did they do this you might ask. They said they put a little drop on their tongues. Spiders have tongues????

My new Zentangle buddies!
Now I just have to get the drugs...caffeine will be easy.
Finding their tongues will be a little harder.
