The rules are as follows:
- Find a partner you'd like to play with.
- Look for 10 good ingredients which you'd typically add to a smoothie.
- Look for 10 bad ingredients which would ruin the taste of a smoothie.
- Note down all the ingredients on separate papers and put in a hat.
- A player will now choose from the hat and add the ingredient noted on the paper into the blender.
- Both players will repeat the process until all the ingredients have been drawn from the hat.
- Once the ingredients have run out both players will blend their 'smoothies' with the help of a blender.
- Now the challenge for the players is to completely finish their smoothies.
- Whoever finishes their smoothie first; simply wins!
Over here is a video of Ariana Grande taking part in the Smoothie Challenge done at Nick Studios. This challenge is done slightly differently to the rules mentioned above. However its a nice alteration to the usual way of completing the challenge.
This is a video of iisuperwomanii completing this challenge similar to the rules mentioned above in this post.
