About Gifts Under $25
Small budget, real science. Every product here costs less than $25 before shipping, which makes them good stocking fillers, party gifts and class sets. Most are boxed STEM experiments for children from about 8 years old; a few are electronics modules and parts for makers.
Shipping is calculated once per order and becomes free over $260, so several kits for a class cost little more to send than one.
