“These versatile modelling Toobers provide hands-on learning experiences in biology and chemistry. Students can model DNA or create protein structures and explore basic protein folding principles. Toobers are flexible foam rods which have a soft wire core that allows them to hold their shape well and they can be simply straightened out afterwards and re-used. Length: 4 feet (120cm) long . Push pins not included. See also ‘Amino Acid Starter Kit.’
