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.
Seed should be stored cold prior to sowing or stratifying. Allow the seed to warm to room temperature, then soak in water 24 hours, for most species. Seed must be moist to stratify. Most seeds are dried to below 10 percent moisture for best storage. Seed below 10 percent moisture does not stratify well and may just sit dormant. The moisture level must be increased to 60 percent or more to allow the seed to begin to stratify.
