Use Touch Interest without it glitching with other objects?

Im making a kamehameha script but when i put a touch interest in the beam of the kamehameha it moves around and glitches and it wont stand still, goes up even tho i anchored it please help without touch interest https://cdn.discordapp.com/attachments/343099799928832000/356955649030094849/without.PNG with touch interest https://cdn.discordapp.com/attachments/343099799928832000/356955595338940419/with_touchinterest.PNG
