You can check your stores for any almonds in packages, just make sure they are raw almonds, not roasted. lol.
I soaked mine for a day, then peeled the brown layer off the almond seeds, and planted the very soft white seed in dirt. I don't think I peeled the first one, but did to these. I'll let you know if any of them sprout.
I also bought a thing at a craft store, it's a little green house with seeds for a Banana tree. Says it will grow Bananas from the seeds. I'm pretty sure they won't be the Dole type of Bananas we see in the stores, and will most likely have large seeds inside, but will still be interesting to grow.
