I believe there is a commercial lab dealing with extraction of salicylic 
acid from willow, which gave us the idea for aspirin.

The idea for Velcro orginally came when someone looked at sticktights 
stuck to their clothes under a microscope.

Flash powder (lycopodium spores) was once used in photography and to keep 
pills from sticking together.

Make "coffee" from seeds of Kentucky coffee tree (Gymnocladus 
dioicus) seeds.

Carolina Biological Supply sells vanilla bean pods. Extract 
them with alcohol and make vanilla extract.

Collect sassafras roots and make sasparilla.

Make candles from bayberry fruits. Grow citronella and make insect 
repellant candles.

Make insect sprays with pyrethrum, garlic, or tobacco (nicotine).

Collect fern fiddleheads and make a salad.

Get chia seeds (Salvia hispanica) and make a Chia Pet using a sponge or 
mix with water to make an edible gruel. Chia was a major food crop of the 
Aztecs. 

Extract any of the oil seeds (sunflower, peanut, safflower, etc.) to get 
cooking oil.

Anna Lewington's book Plants for People (1990. Cambridge Univ. Press) has 
lots of other ideas.
