Red bull and DaphniaFeatured science projectScience project video


The hypothesis that  Red Bull drink increases the heart beat of Daphnia is proven to be true.

The invigorating experience and feeling gained after drinking a bottle of Red Bull is probably due to the caffeine in the drink. The actual level of caffeine in the Red Bull drink may not be the same in different countries due to different regulatory controls and laws of each country.

Also consider

The experiment can also be done by using other energy drinks like Monster.

Try to repeat the experiment by adjusting the room temperature.
