Adults across the U.S. are turning to lemonade stands, traditionally a children’s activity, as a way to supplement their income.

People in their 20s and 30s are setting up stands at farmers markets, festivals, and concerts to pay off bills and debt.

For instance, Malia Blake, 26, from Washington, D.C., started “Malia’s Main Squeeze” to tackle her $40,000 debt.

She now earns $1,000 to $1,500 per event selling lemonade for $8 a cup, Fox Business has reported.

Similarly, Elizabeth Williams, 23, from Kentucky, runs a mobile lemonade stand that generated $80,000 last year, helping her pay off a student loan and cover living expenses.

However, potential lemonade entrepreneurs should be aware of varying local laws regarding food and drink sales.
