Alright going to wrap up the Harry Potter and Back To Hogwarts Day with an edible science experiment that I think Fred and George would have served at their shop. Hope you enjoy; cheers!
1/4 Tsp of Baking Soda
1 Tbsp of Sugar
1/4 Cup of Water
Cups to Hold Liquid
1) To juice the lemons, just cut lemons in half and squeeze into the cup. Should be roughly a 1/4 cup of juice. Set aside. Note: 1/4 Cup of Bottled Lemon Juice could be substituted for lemons, but you may need to adjust water and sugar.
2) Pour 1/4 cup of water into a different cup and mix 1 tablespoon of sugar into the water, until the sugar is completely dissolved. Set aside water/sugar mixture.
3) In the cup with the lemon juice, make sure any seeds are removed and then add 1/4 tsp of baking soda. Watch the bubbling reaction-- it's the same reaction that happens in a baking soda and vinegar reaction!
4) Now add the bubbling lemon juice to the water/sugar mixture and stir. You now have fizzing lemonade! Take a sip and enjoy!
Note: play around with adding more water or sugar if the lemonade tastes too sour or add another 1/4 tsp of baking soda if you want more fizzing.
Safety disclaimer: Like many things, baking soda is not safe to be ingested in large quantities, so please supervise young children. It is safe for them to consume a small amount such as the quantity in this fizzing lemonade experiment.
