High Reward Stocks

Any risky, high potential stocks to jump on that have a chance at blowing up in the next few years? Frankly, I don’t have some crazy amount of money to invest in the first place, so I’m willing to go super high risk and am not scared of losing big. Something in the medical industry or energy sectors would be preferable, but I don’t really care what it is. Just wanna have some fun and take a chance.
