Article V explains the amendment process, which is different and more difficult than the process for making laws. When two-thirds of the Senate and two-thirds of the House of Representatives vote to change the Constitution, an amendment goes to the state legislatures for a vote.
Another way to use the fridge for brief cold stratification is to plant the seeds in individual jiffy pellets and put them in either a plastic covered container (such as for home baking little bread loaves) or in a store-bought greenhouse flat. Depends on how much room you have in your fridge.
Sow seed directly outdoors in the fall or plant stratified seed in the spring. Seed of the sugar maple (Acer saccharum) should be stratified for 40 to 90 days at 33 to 41 F, while seed of the Norway maple (Acer platanoides) require 90 to 120 days at 41 F. Plant the seed (fruit) 1/4 to 1 inch deep.
