It has become tradition to host a triple party for my dad, my husband and my son whose birthdays all fall the same week at the end of May/beginning of June. And, because I am practically the same person as my mom, it has become tradition for these parties to have a theme.
The invitations have been mailed. In case someone couldn't crack the numeric code on the front, here's a hint: iron the back of the card to reveal the date and time written in invisible ink. This is probably super annoying but I had fun!
I've already got pipet "straws" and a few Erlenmeyer flasks so really, all that remains, is deciding whether the cake should be a model of an atom or a solar system.
Here is where I found the cool (free) website to make the periodic table words.
And I did some invisible ink tests. Lemon juice works better than milk milk. And though the website said acid was the active ingredient vinegar does not work at all. I used a q-tip to write with lemon juice, let it dry and mailed it. Both ironing and holding over a candle worked to reveal the words.
