I didn't want to get his teachers something totally useless so when I saw this idea, I knew it was perfect. I made my own version so I could customize it a bit (here's the link to the free printable) and I used these acrylic tumblers because they were the cheapest I could find (he has four teachers) but these are another great option.
Living in Arizona in the summer means that hydration is vital and I know that these reuseable acrylic tumblers have been saving my life this pregnancy. I love to fill them all the way to the top with ice and it helps me drink so much more water!
I filled them with the Trader Joe's brand of Emergen-C with a little note about my favorite way to use them (per my friend, Lela's idea). Pour one packet into the bottom of the cup and then fill with ice. Add about 1/4 cup of your favorite juice (I like peach nectar) and then carefully fill the rest with infused sparkling water (I use Trader Joe's berry) - pour slowly because it will fizz a lot. I like this better than any kind of soda out there and it has way less calories plus the added vitamins!
