Scientific Experiments

Introduction
Dad located a book of simple science experiments.

Key Phrase
Once the briefcase was unlocked, it was discovered that the items within the briefcase all had single letters attached to them.

Using the information gleaned from the night six barcode (as unlocked by the Harp), this referenced specific experiments inside the book.

If you sorted the experiments by order in the book, and read the associate letters from the items in the briefcase, this revealed the phrase LOLOGRAM.

Email Address
This turned out to be an email address at lolaroid.photo (the website listed on all the Lolaroid cards) that when emailed, with the subject line with the name of the person with the missing email address Eliza Howser, sent each person that emailed it a unique email address containing a coded phrase for how many ingredients their new product required.

Once those numbers were all collected, they were then applied to a periodic table, marking out the element associated with that number.

Result
This has revealed another probable great name, RON.
