Disclaimer: Wishes are more likely to come true if they are realistic and/or benefiting others selflessly. However, you can still wish for whatever you want. It may come true anyway. Wishes also are not on a time schedule and like to come true in odd ways so you must be very specific. But, sometimes you are limited on wishing time (like 11:11) and it can cost you that wish.
Everyone knows this! Take a penny, make a wish, and toss it in. If you have a coin with a higher denomination, the more likely your wish will come true. If the fountain is multi-tiered then you have to aim. The higher you get the coin, the higher your chances of success.
- Star light, star bright,
- The first star I see tonight;
- I wish I may, I wish I might,
- Have the wish I wish tonight
This might be more of a good luck charm, but I feel like--if you're lucky enough to find one--you get to wish on it too.
Give an Offering
Some people would count this more like a prayer. You give something of value to your idol, tiny temple, tree spirits, etc. Then, you wish for what they can offer in return like good grades or a safe trip.
One of the biggest mistakes College Park students make with Testudo is they give him basically trash like mostly empty Starbucks drinks.
