Butter Making (Shake Cream in a Jar)

Heavy cream shaken in a jar turns into real butter — science you can spread on toast.

Steps

1. Pour heavy whipping cream into a jar with a tight lid, filling it no more than halfway.
2. Seal the lid tightly and let your preschooler shake it vigorously.
3. Keep shaking, taking turns helps, until the cream separates into a lump of butter and liquid buttermilk.
4. Drain the buttermilk, rinse the butter under cold water, and spread it on crackers or toast to taste.

Notes

This takes 10-15 minutes of steady shaking — pass the jar around if little arms get tired.
