Accurate Measurement of Flammable Gases. Combination instruments provide the flexibility to do general-purpose safety monitoring, as well as detection of very high levels of flammable gases and vapors. TODAY there are a variety of sensors used to detect flammable gases.
I saw Van Halen on the 1984 tour, there was no extra keyboard player. Ed played some keyboard on the intro into Jump and some in the middle, but stuck with the guitar for the solo. He did a solo keyboard pice as well seperately.
Jump by Van Halen is featured in Mattress, the twelfth episode of Season One. It is sung by the New Directions, with Artie, Finn, Mercedes, and Rachel singing solos. The song is sung while they film a commercial for the store Mattress Land that Rachel gets them cast in. It features the Glee kids jumping on multiple mattresses as well as singing, rolling, and flipping.
